s-1-(combination) and Pharyngeal-Neoplasms

The most common sites of recurrence after liver transplantation for hepatocellular carcinoma (HCC) have been reported to be the liver, lung, bone, and adrenal glands, but there have also been many reports of cases of multiple recurrence. The prognosis after recurrence is poor, with reported median survival after recurrence of HCC ranging from 9 to 19 months. Here, we report a case of long-term survival after recurrence of pharyngeal metastasis following living-donor liver transplantation (LDLT) for HCC within the Milan criteria, by resection of the metastatic region and cervical lymph node dissection.. A 47-year-old man with a Model End-stage Liver Disease (MELD) score of 11 underwent LDLT for HCC within the Milan criteria for liver cirrhosis associated with hepatitis B virus infection, with his 48-year-old elder brother as the living donor. One year and 10 months after liver transplantation, he visited a nearby hospital with a chief complaint of discomfort on swallowing. A pedunculated polyp was found in the hypopharynx, and biopsy revealed HCC metastasis. We performed pharyngeal polypectomy. Two years later, cervical lymph node metastasis appeared, and neck lymph node dissection was performed. Although recurrence subsequently occurred three times in the grafted liver, the patient is still alive 12 years and 10 months after recurrence of pharyngeal metastasis. He is now a tumor-free outpatient taking sorafenib.. It is necessary to recognize that the nasopharyngeal region is a potential site of HCC metastasis. Prognostic improvement can be expected with close follow-up, early detection, and multidisciplinary treatment, including radical resection.

The goals of treatment for head and neck cancer are cure and organ-function preservation. For organ preservation, primary treatment via radiotherapy alone is thought to be insufficient for Stage II squamous cell carcinoma of the larynx, oropharynx or hypopharynx. The objective of the present study was to investigate the efficacy and safety of concurrent chemoradiotherapy with S-1 for patients with Stage II squamous cell carcinoma of the pharynx or larynx for primary organ preservation.. Previously untreated patients with Stage II squamous cell carcinoma of the larynx, oropharynx or hypopharynx received three courses of S-1 (40 or 50 mg twice a day; 2 weeks of administration followed by 1 week of rest every 3 weeks) during conventional radiotherapy (a single daily fraction of 1.8 Gy) to a total dose of 70.2 Gy. The primary endpoint was the local control rate at 3 years.. From August 2009 to October 2012, 37 patients were evaluated for the study. The overall response rate was 100%. The 3-year local control rate was 89.0% (95% confidence interval, 78.9-99.2%), and the 3-year overall survival rate was 97.2% (95% confidence interval, 91.8-100%). Mucositis and dermatitis in the radiation field were the most common acute adverse events observed. The rates of Grade 3 mucositis and dermatitis were 27 and 35%, respectively. No patients experienced Grade 4 acute adverse events. The treatment completion rate was 89.2%.. Concurrent chemoradiotherapy with S-1 was safe and effective in improving local control for Stage II squamous cell carcinoma of the pharynx or larynx.

The present study aimed to retrospectively analyze the long-term efficacy and toxicity of concurrent chemoradiotherapy with nedaplatin and S-1 for head and neck squamous cell carcinoma.. The study enrolled 53 patients (23 with stage II disease, 13 with stage III disease, and 17 with stage IV disease). S-1 was administered orally twice a day for 14 days, followed by a two-week rest period. Nedaplatin was intravenously administered on day 4. Where possible, two courses of chemotherapy were performed. Radiotherapy was started with the administration of S-1. We analyzed the clinical response, survival rate, acute adverse events, and late swallowing toxicity.. The complete response rates for the primary tumor and neck lymph node metastases were 94.3% and 79.3%, respectively. The five-year overall survival rate was 79.5%, the five-year disease-specific survival rate was 84.8%, and the five-year relapse-free survival rate was 73.7%. The main acute adverse events were leukopenia, neutropenia, mucositis, and dermatitis. No patient had severe nephrotoxicity. Late swallowing toxicity was observed in 13 patients.. The low toxicity, and low nephrotoxicity of chemoradiotherapy with nedaplatin and S-1 have a positive impact on long-term survival. The combination of nedaplatin and S-1 can be used instead of cisplatin and 5-fluorouracil as a safer regimen, especially in patients with some complications and those requiring treatment in an outpatient setting.

Adverse events and therapeutic effects were analyzed in patients with pharyngeal or advanced laryngeal squamous cell carcinomas(SCCs)receiving concurrent chemoradiotherapy (CCRT) with S-1 or weekly CDDP between 2004 and 2007. Low-dose CDDP (25 mg/m2) was administered once a week and S-1 (65 mg/m2) was administered for 3 weeks with one-week rest during conventional radiation with 2 Gy/fraction. Both of the two CCRT regimens showed little toxicity with grade 4 toxicities in less than 5%of the patients. However, CCRT with S-1 more frequently induced grade 3 and 4 oral mucositis than CCRT with CDDP. As a result, the completion rate of CCRT with S-1 was lower than that of CCRT with CDDP. The two regimens achieved a similar complete response rate of the primary sites, local control rate(LCR)and larynx preservation rate; the LCR for T1 and 2 disease was more than 70%. However, the LCR for T3 or 4 disease by the two regimens was less than 50%. CCRT with S-1 showed significantly higher LCR in patients with poorly or undifferentiated SCCs than those with well or moderately-differentiated SCCs. It is suggested that the two CCRT regimens are useful treatment modalities for patients with locally(primary site)non-advanced pharyngeal or laryngeal SCCs, and that CCRT with S-1 is highly sensitive to poorly or undifferentiated SCCs. In order to achieve local control and larynx preservation, more intensive CCRT might be necessary for patients with locally(primary site)advanced pharyngeal or laryngeal SCCs.
