Managing patients treated with bevacizumab combination therapy.
    Oncology, 2005, Volume: 69 Suppl 3

    The anti-angiogenic agent bevacizumab (Avastin) has been rationally designed to target vascular endothelial growth factor (VEGF), a key mediator of tumor angiogenesis. Based on its limited roles in adults, VEGF inhibition using bevacizumab would be expected to have limited side effects. Furthermore, because its mechanism of action is different to that of standard chemotherapeutic agents, bevacizumab would not be expected to cause typical cytotoxic agent-related toxicity or to exacerbate the toxicity of concomitant chemotherapy. We have reviewed clinical trials published to date, primarily in metastatic colorectal cancer, and describe the safety profile of bevacizumab. The review focuses on hypertension, proteinuria, arterial thrombosis, effects on wound healing, bleeding and gastrointestinal (GI) perforation, which are the principal bevacizumab-related events seen in clinical trials. These events are for the most part mild to moderate in severity and clinically manageable (hypertension, proteinuria, minor bleeding) or occur uncommonly (wound healing complications, GI perforations and arterial thrombosis). The side-effect profile of bevacizumab makes it a suitable adjunct to standard chemotherapy in settings where efficacy has been demonstrated, and it is now approved for use in the USA, the European Union and other markets worldwide.

[Colon cancer in pregnancy].
    Journal de chirurgie, 2003, Volume: 140, Issue:4

    Colon cancers arise only rarely in the course of a pregnancy. Yet colon obstruction, perforation and metastatic spread seem to occur more frequently in this setting than with the average colon cancer. Perhaps this is due to the immunotolerance which accompanies pregnancy. No case of epidermoid (squamous cell) cancer of the colon has been previously described in a pregnant woman. This conjunction has a catastrophic prognosis: the diagnosis of colon tumor is delayed since symptoms are masked by the pregnancy, and epidermoid colon cancer is a particularly aggressive lesion. A major sub-diaphragmatic surgical procedure can be performed with reasonable safety to mother and fetus. Radiotherapy is contraindicated. Neo-adjuvant chemotherapy can be administered although the risks to the fetus are not well known. During the first trimester, a therapeutic abortion can be proposed to optimise the treatment of the mother. During the second and third trimesters, treatment of the mother exposes the fetus to the risk of malformations or premature delivery; delay in maternal treatment in hopes of prolonging the pregnancy in order to obtain a viable neonate diminish the chances of maternal survival.

Multicenter feasibility study of combination therapy with fluorouracil, leucovorin and paclitaxel (FLTAX) for peritoneal disseminated gastric cancer with massive ascites or inadequate oral intake.
    Japanese journal of clinical oncology, 2012, Volume: 42, Issue:9

    Oral fluoropyrimidine plus cisplatin is a standard treatment for advanced gastric cancer, but patients with severe peritoneal metastasis often cannot tolerate this regimen. The aim of this study was to assess the feasibility of fluorouracil, l-leucovorin and paclitaxel therapy in such patients.. In the first phase of the study, we investigated the maximum tolerated dose and recommended dose in Cycle 1 of fluorouracil, l-leucovorin and paclitaxel, at two dose levels [Level 1 (n = 6): 5-fluorouracil/l-leucovorin/paclitaxel = 500/250/60 mg/m(2); Level 2 (n = 6): 600/250/80 mg/m(2) on Days 1, 8 and 15, every 28 days]. Nineteen additional patients at the recommended dose level were enrolled in the second phase to investigate the feasibility of fluorouracil, l-leucovorin and paclitaxel therapy. The primary endpoint in the second phase was the completion rate of two cycles.. Dose-limiting toxicities were observed in a patient at Level 1 with Grade 4 gastrointestinal perforation (the site of primary tumor), and in two patients at Level 2 with Grade 3 febrile neutropenia and Grade 3 infection, respectively. In Cycle 2, treatment-related death occurred at Level 2 in one patient who had Grade 4 febrile neutropenia with pneumonia. The maximum tolerated dose was set at Level 2, and the recommended dose was determined as Level 1. In the second phase, the completion rate of two cycles was 92% and the ascites response was 44%. Median progression-free survival was 4.2 months and overall survival was 8.0 months. Grade 3/4 neutropenia was observed in 12% of patients.. Fluorouracil, l-leucovorin and paclitaxel at Level 1 is feasible as first-line treatment for peritoneal disseminated gastric cancer patients with massive ascites or inadequate oral intake.

Primary mFOLFOX6 plus bevacizumab without resection of the primary tumor for patients presenting with surgically unresectable metastatic colon cancer and an intact asymptomatic colon cancer: definitive analysis of NSABP trial C-10.
    Journal of clinical oncology : official journal of the American Society of Clinical Oncology, 2012, Sep-10, Volume: 30, Issue:26

    Major concerns surround combining chemotherapy with bevacizumab in patients with colon cancer presenting with an asymptomatic intact primary tumor (IPT) and synchronous yet unresectable metastatic disease. Surgical resection of asymptomatic IPT is controversial.. Eligibility for this prospective, multicenter phase II trial included Eastern Cooperative Oncology Group (ECOG) performance status 0 to 1, asymptomatic IPT, and unresectable metastases. All received infusional fluorouracil, leucovorin, and oxaliplatin (mFOLFOX6) combined with bevacizumab. The primary end point was major morbidity events, defined as surgical resection because of symptoms at or death related to the IPT. A 25% major morbidity rate was considered acceptable. Secondary end points included overall survival (OS) and minor morbidity related to IPT requiring hospitalization, transfusion, or nonsurgical intervention.. Ninety patients registered between March 2006 and June 2009: 86 were eligible with follow-up, median age was 58 years, and 52% were female. Median follow-up was 20.7 months. There were 12 patients (14%) with major morbidity related to IPT: 10 required surgery (eight, obstruction; one, perforation; and one, abdominal pain), and two patients died. The 24-month cumulative incidence of major morbidity was 16.3% (95% CI, 7.6% to 25.1%). Eleven IPTs were resected without a morbidity event: eight for attempted cure and three for other reasons. Two patients had minor morbidity events only: one hospitalization and one nonsurgical intervention. Median OS was 19.9 months (95% CI, 15.0 to 27.2 months).. This trial met its primary end point. Combining mFOLFOX6 with bevacizumab did not result in an unacceptable rate of obstruction, perforation, bleeding, or death related to IPT. Survival was not compromised. These patients can be spared initial noncurative resection of their asymptomatic IPT.

Bowel perforation due to methotrexate therapeutic error: an insidious adverse reaction.
    European review for medical and pharmacological sciences, 2021, Volume: 25, Issue:5

    Methotrexate (MTX) is widely used in the treatment of rheumatic and non-rheumatic disorders. Severe adverse effects are often associated with therapeutic errors, such as daily intake rather than weekly intake. Among them, the risk of bowel perforation is extremely rare (0.1%). We describe a case of bowel perforation, occurred following daily intake of MTX.. A 68-year-old man was prescribed to take MTX 7,5 mg orally once a week, while waiting for switch to abatacept for a recent reactivation of rheumatoid arthritis. After 10 days he started having pharyngodynia, hematochezia and general malaise. At medical examination he presented oral and nasal mucositis; moreover, blood exams showed thrombocytopenia. The anamnesis revealed that he had been taken the prescribed dosage of MTX daily, instead of weekly. Therapy with Lederfolin 1000 mg (mg/m²/die) and urine alkalinization started. After 7 days of hospitalization, there was an abrupt worsening of clinical conditions and an emergency CT scan revealed millimetric gas bubbles indicating bowel perforation. The patient underwent an emergency exploratory laparotomy that resulted in peritoneal toilette and sigma resections. Anatomopathological findings were suggestive of MTX poisoning.. The patient was discharged on the 17th day in good clinical condition.

Primary Tumor-Related Complications Among Patients With Unresectable Stage IV Colorectal Cancer in the Era of Targeted Therapy: A Competing Risk Regression Analysis.
    Diseases of the colon and rectum, 2021, 09-01, Volume: 64, Issue:9

    Whether prolonged survival with current chemotherapy using molecular target agents has changed the rate of primary tumor-related complications in patients with unresectable stage IV colorectal cancer is unclear.. This study aimed to investigate the rate of primary tumor-related complications among patients receiving targeted therapy as compared with patients receiving chemotherapy without molecular target agents.. This was a retrospective review of data from a prospectively maintained database.. The study was conducted at a high-volume multidisciplinary tertiary cancer center in Japan.. Subjects were 352 consecutive patients with unresectable stage IV colorectal cancer who received systemic chemotherapy without primary tumor resection from 2001 to 2015. Patients were categorized into nontargeted and targeted groups according to the use of molecular target agents.. Complication rates attributed to primary tumors were measured.. Of the 352 patients, 159 were categorized into the nontargeted group and 193 patients into the targeted group. Competing risk-adjusted univariate analysis revealed that the primary tumor-related complication rates in the nontargeted group were 6.9% (95% CI, 3.8%-11.9%) at 1 year and 8.2% (95% CI, 4.8%-13.8%) at 2 years, whereas the targeted group had complication rates of 11.5% (95% CI, 7.5%-16.6%) at 1 year and 16.7% (95% CI, 12.4%-23.3%) at 2 years. Multivariate analysis revealed that the targeted group was ≈2 times more likely to have primary tumor-related complications (subdistribution HR = 2.04 (95% CI, 1.12-4.01); p = 0.020). Median survival time was 12.0 months in the nontargeted group and 24.1 months in the targeted group (p < 0.001).. This study was limited by the retrospective design.. Targeted therapy was associated with a significantly increased risk of primary tumor-related complications during chemotherapy. However, targeted therapy also improved overall survival, making it a tolerable therapy. See Video Abstract at http://links.lww.com/DCR/B536.. ANTECEDENTES:No está claro si la supervivencia prolongada con la quimioterapia actual utilizando agentes moleculares dirigidos ha cambiado la tasa de complicaciones relacionadas con el tumor primario en pacientes con cáncer colorrectal en estadio IV irresecable.OBJETIVO:Este estudio tuvo como objetivo investigar la tasa de complicaciones relacionadas con el tumor primario entre los pacientes que reciben terapia dirigida, en comparación con pacientes que reciben quimioterapia sin agentes moleculares dirigidos.DISEÑO:Revisión retrospectiva de datos de una base de datos mantenida prospectivamente.ESCENARIO CLINICO:Centro oncológico de tercer nivel multidisciplinario de alto volumen en Japón.PACIENTES:352 pacientes consecutivos con cáncer colorrectal en estadio IV irresecable que recibieron quimioterapia sistémica sin resección del tumor primario entre 2001 y 2015. Los pacientes se clasificaron en grupos dirigidos y no dirigidos según el uso de agentes moleculares dirigidos.PRINCIPALES MEDIDAS DE VALORACION:Tasas de complicaciones debidas a tumores primarios.RESULTADOS:De los 352 pacientes, 159 se clasificaron en el grupo no dirigido y 193 pacientes en el grupo dirigido. El análisis univariado ajustado al riesgo competitivo reveló que las tasas de complicaciones primarias relacionadas con el tumor en el grupo no dirigido fueron del 6,9% (intervalo de confianza (IC) del 95%, 3,8 - 11,9%) al año y del 8,2% (IC del 95%, 4,8%). - 13,8%) a los dos años, mientras que el grupo dirigido tuvo tasas de complicaciones del 11,5% (IC del 95%, 7,5 - 16,6%) al año y del 16,7% (IC del 95%, 12,4 - 23,3%) a los dos años. El análisis multivariado reveló que el grupo dirigido tenía aproximadamente dos veces más probabilidades de tener complicaciones relacionadas con el tumor primario (razón de riesgo de subdistribución, 2,04; IC del 95%, 1,12 a 4,01; p = 0,020). La mediana del tiempo de supervivencia fue de 12,0 meses en el grupo no dirigido y de 24,1 meses en el grupo dirigido (p <0,001).LIMITACIONES:Este estudio estuvo limitado por el diseño retrospectivo.CONCLUSIONES:La terapia dirigida se asoció con un riesgo significativamente mayor de complicaciones relacionadas con el tumor primario durante la quimioterapia. Sin embargo, la terapia dirigida también mejoró la SG, convirtiéndola en una terapia tolerable. Consulte Video Resumen en http://links.lww.com/DCR/B536.

Early small bowel perforation due to aflibercept.
    Drug discoveries & therapeutics, 2017, Nov-22, Volume: 11, Issue:5

    In patients with malignancy who receive aflibercept based chemotherapy, gastrointestinal perforation is among the reported adverse events with a prevalence of 1.9%. This complication may lead to mortality up to 10.8%. We here report a case of small bowel perforation that occurred fifteen days after the first cycle of aflibercept in a 58-year old female who had metachronous colorectal liver metastases. Emergency laparotomy was performed and revealed a small bowel perforation without any anastomotic dehiscence. Surgery was followed by uneventful outcome. The use of aflibercept in patients with malignancy may be associated with very early gastrointestinal perforation and this should be known by oncologist and surgeons.

[A Case of Fournier's Gangrene Caused by Small Intestinal Perforation during Bevacizumab Combination Chemotherapy].
    Gan to kagaku ryoho. Cancer & chemotherapy, 2016, Volume: 43, Issue:7

    A 51-year-old man underwent abdominoperineal resection for advanced rectal cancer at a hospital. He attended our outpatient clinic 58 months later with pain in the external genitalia, and was diagnosed with local pelvic recurrence and metastasis to the para-aortic lymph node and both adrenal glands. He received a total of 30 Gy of radiation for analgesia; subsequently, chemotherapy(mFOLFOX6 plus bevacizumab)was initiated. However, extreme left buttock and left femoral pain developed after the 6 courses of chemotherapy. Abdominal CT revealed Fournier's gangrene caused by small intestinal perforation. Emergency drainage under spinal anesthesia was immediately performed. Two additional drainage procedures were required thereafter and an ileostomy was constructed. The patient was discharged 100 days after the initial drainage. This is an extremely rare example of a bevacizumab-related small intestinal perforation that developed into Fournier's gan- grene.

[Conversion Therapy of Initially Unresectable Rectal Cancer with Perforation via FOLFOX4 Chemotherapy].
    Gan to kagaku ryoho. Cancer & chemotherapy, 2015, Volume: 42, Issue:12

    We describe a case of perforated rectal cancer that became curatively resectable after FOLFOX4 chemotherapy. An 81- year-old woman was transferred to our hospital with a diagnosis of bowel perforation. She underwent emergency transverse colostomy, peritoneal lavage, and the insertion of indwelling drainage tubes, because the perforated rectal cancer was considered unresectable. After recuperation, she received chemotherapy consisting of FOLFOX4 and bevacizumab. Owing to a good response to the treatment after 4 months, rectal resection was achieved curatively. Wound dehiscence occurred as a postoperative complication. The patient chose not to receive adjuvant chemotherapy. Currently, she has been alive for more than 1 year 3 months after resection without recurrence.

Evaluation of the necessity of primary tumor resection for synchronous metastatic colorectal cancer.
    Surgery today, 2014, Volume: 44, Issue:12

    We evaluated the need for primary tumor resection in patients with colorectal cancer (CRC) and synchronous unresectable metastases who underwent chemotherapy, and identified the associations between the primary tumor characteristics and risk of intestinal obstruction or perforation.. We retrospectively analyzed the survival and complication rates of patients with synchronous metastatic CRC treated between April 2005 and December 2011.. Of 131 patients, 68 underwent primary tumor resection before chemotherapy, and 63 were treated without resection before chemotherapy. The overall survival (OS) did not significantly differ between the two groups (log-rank P = 0.53). In the resection group, 12 patients (17.6%) developed postoperative complications. In the non-resection group, 16 patients (25.4%) required surgical intervention owing to obstruction or perforation during their treatment. Surgical intervention did not affect the OS. A circumferential tumor was a risk factor for obstruction or perforation of the colorectum in non-resected patients (odds ratio = 11.163; P = 0.006).. Resection of primary tumors before chemotherapy is unnecessary in selected patients with synchronous metastatic colorectal cancer. A circumferential tumor is a risk factor for obstruction or perforation during chemotherapy in cases without primary tumor resection.

[A case of duodenal perforation during mFOLFOX6 treatment for metastatic sigmoid colon cancer].
    Gan to kagaku ryoho. Cancer & chemotherapy, 2010, Volume: 37, Issue:13

    We present a case of metastatic sigmoid colon cancer causing duodenal perforation during modified FOLFOX6 chemotherapy. The patient was a 68-year-old man who underwent sigmoidectomy for an advanced sigmoid cancer in September 2007. He has been received mFOLFOX6 chemotherapy for multiple liver metastases since January 2009. In March 2010, the patient complained of abdominal pain during the 24th course of chemotherapy, and was admitted to our hospital. On admission, his vital signs were normal, and abdominal findings revealed no peritonitis signs. An abdominal CT scan showed free air and fluid collection on the first day of admission. The patient was diagnosed with gastrointestinal perforation, and underwent emergency operation for abdominal drainage. The leakage of biliary fluids was recognized at the drain to the Winslow postoperatively. It ceased on the 25th admission day, and an upper gastrointestinal examination showed good passage of fluids and no leakage at the duodenum. However, the patient died 36 days after admission from remarkable pleural effusion and respiratory failure.

Perforated mixed carcinoid-adenocarcinoma in transverse colon and at gastroenterostomy site: case report.
    World journal of surgical oncology, 2010, Dec-22, Volume: 8

    Goblet cell carcinoid of the large intestine is a rare neoplasm, usually located in ascending colon and rectum. A 60-year-old male patient underwent surgery after the diagnosis of acute abdomen. Exploratory laparotomy revealed perforation with a diameter of 1 cm at the site of the previously performed gastroenterostomy and dilatation of the right colic flexure, secondary to a solid obstructive mass located in the mid-portion of transverse colon. Histopathological investigation of the biopsies, taken from the gastroenterostomy site and the tumor, revealed mixed carcinoid-adenocarcinoma with carcinoid component, predominantly composed of goblet cells. Three cycles of FOLFOX-4 protocol was administered. Following respiratory distress secondary to pulmonary metastasis, the patient's condition deteriorated and subsequently died in the fourth postoperative month. Our aim with this paper is to point out that more cases should be reported for more effective diagnosis, histopathological study, clinical investigation, treatment and prognosis of this specific neoplasm.

[Prognostic analysis of 443 cases of stage II colorectal cancer and the value of adjuvant chemotherapy].
    Ai zheng = Aizheng = Chinese journal of cancer, 2009, Volume: 28, Issue:9

    Prognosis of stage II colorectal cancer varies. Whether or not to perform adjuvant chemotherapy on patients with stage II colorectal cancer is controversial. This study was to explore the prognostic factors for the patients with stage II colorectal cancer and evaluate the effect and the necessity of adjuvant chemotherapy.. Between January 2000 and January 2005, 443 patients with stage II colorectal cancer receiving radical surgery at Sun Yat-sen University Cancer Center were retrospectively analyzed. The overall survival rate and survival curve were analyzed using the Kaplan-Meier method and the log-rank test. The univariate and multivariate prognostic analyses were performed by the Cox regression model. Patients with or without chemotherapy (Xelox/Folfox regimen) with high-risk factors were analyzed respectively.. The median follow-up time was 59 months, and the 3-and 5-year survival rates were 88.4% and 82.5%, respectively. Univariate analysis showed that intestinal obstruction or perforation, diabetes mellitus, inadequate surgical margin, and the number of sampled nodes < 9 were poor prognostic factors. Patients with intestinal obstruction or perforation, the number of sampled nodes < 9 achieved higher 5-year survival (80% and 86%) undergoing adjuvant chemotherapy than those receiving surgery alone (67% and 64%).. The prognosis of colorectal cancer patients with intestinal obstruction or perforation, diabetes mellitus, inadequate surgical margin, and the number of sampled nodes < 9 are relatively poor. Adjuvant chemotherapy is recommended to patients with intestinal obstruction, perforation or sampled nodes < 9.

[Ischemic anastomotic bowel perforation during treatment with bevacizumab 10 months after surgery].
    Der Chirurg; Zeitschrift fur alle Gebiete der operativen Medizen, 2008, Volume: 79, Issue:4

    Bevacizumab (Avastin) is a monoclonal antibody against vascular endothelial growth factor (VEGF) receptor that has demonstrated increased overall survival when added to standard chemotherapy regimens in patients with metastatic colorectal cancer. Gastrointestinal perforation is a known risk factor of unknown etiology associated with the use of bevacizumab.. We report a 61-year-old woman with adenocarcinoma of the colon ascendens who underwent hemicolectomy and adjuvant chemotherapy with oxaliplatin, 5-fluorouracil, and leucovorin. Eight months after the operation, we started therapy with bevacizumab combined with irinotecan, 5-fluorouracil, and leucovorin due to disease progression. Two months after completion of this therapy, ischemic anastomotic bowel perforation occurred and a resection of the anastomosis was performed. Because of anastomotic insufficiency 8 days later, a further revision had to be done and the terminal ileum and the colon were brought out through a stoma.. This case is unusual because the time interval between the primary operation and the application of bevacizumab is regarded as safe with regard to the risk of perforation. An ischemic genesis of the perforation was considered on the basis of the histopathological workup. In case of perforations during therapy with bevacizumab, a safe surgical approach should be preferred, i.e., a transient stoma instead of a primary reconstruction of the bowel passage.

Involvement of the appendix in a relapsed case of primary nasal NK/T-cell lymphoma.
    Leukemia & lymphoma, 2000, Volume: 37, Issue:5-6

    We report here a 20-year-old man presenting with primary nasal NK/T-cell lymphoma which showed an aggressive clinical course spreading to the spleen and skin despite various treatments. Eight months after high dose chemotherapy followed by autologous peripheral blood stem cell transplantation, acute appendicitis with perforation occurred and the patient underwent appendectomy. The histopathological diagnosis was NK/T-cell lymphoma of the appendix. Lymphoma of the appendix is extremely rare and the majority of appendiceal lymphomas are of B-cell origin. This is the first report of involvement of appendix by nasal NK/T-cell lymphoma.
