Vitamin K inhibits prostate cancer cells, and an altered expression of vitamin K-dependent proteins in prostate tumors has been linked to their aggressiveness and progression. However, little is known about the effect of vitamin K intake on prostate cancer in human populations.. We evaluated the associations of dietary intake of phylloquinone (vitamin K-1), menaquinones (vitamin K-2), and total vitamin K with the development of prostate cancer among participants in the Prostate, Lung, Colorectal, and Ovarian Cancer (PLCO) Screening Trial.. Dietary intake of vitamin K was assessed with the Dietary Questionnaire (DQX) at baseline and the Dietary History Questionnaire (DHQ) at the third anniversary of randomization by using high-performance liquid chromatography-based food-composition data obtained from the USDA and published studies. During a median follow-up of 11.8 y, 2978 cases of prostate cancer (including 490 advanced cases) were identified from the 28,356 men who completed DQX. Similarly, 2973 cases of prostate cancer (including 647 advanced cases) were documented from the 48,090 men who completed DHQ. Cox proportional hazards regression was used to estimate prostate cancer risk in relation to the dietary intake of vitamin K.. After adjustment for confounders, dietary intakes of phylloquinone, menaquinones, and total vitamin K, assessed with either the DQX or DHQ, were not significantly associated with the risk of advanced, nonadvanced, and total prostate cancer. These results remained virtually the same when vitamin K intake was modeled as a categorical (divided into quintiles) or continuous (per IQR increase) variable or after outliers of total vitamin K intake (defined as a value that falls above the sum of third quartile and twice the IQR) were excluded.. The present study does not suggest that vitamin K intake influences the occurrence of total and advanced prostate cancer in the general US population.

Acne-like skin reactions frequently occur in patients undergoing treatment with drugs inhibiting the epidermal growth factor receptor. Recently, the effects of vitamin K1 containing cream (Reconval K1) as prophylactic skin treatment in addition to doxycycline were explored in a double-blind randomized phase II trial (EVITA) in patients with metastatic colorectal cancer receiving cetuximab. EVITA demonstrated a trend towards less severe skin rash in Reconval K1-treated patients using the tripartite WoMo skin reaction grading score as a thorough tool for quantification of drug related skin reactions. This gender-specific analysis of the EVITA trial evaluated the application of the WoMo score for assessment of epidermal growth factor receptor (EGFR)-related skin toxicities according to treatment arm and gender. To show the robustness of results parametric and non-parametric statistical analyses were conducted. All three parts of the WoMo score independently demonstrated the superiority of the treatment arm (Reconval K1) regarding a significant reduction in acneiform skin reactions in women. Men did not benefit from Reconval K1 cream at any time point in none of the WoMo score analyses. The treatment effect in women was confirmed by the use of skin rash categories based on the final WoMo overall score and mixed effect longitudinal multiple linear regression analysis. The WoMo score represents a sensitive tool for studies exploiting treatments against EGFR mediated acne-like skin rash. Part C of the WoMo score seems to be sufficient for quantification of drug related skin toxicities in further studies. Standard WoMo skin reaction score values for future studies are provided.

Acne-like skin rash is a frequently occurring adverse event associated with drugs against the epidermal growth factor receptor. This randomized vehicle-controlled study investigated the addition of vitamin K1 cream to doxycycline in patients with metastatic colorectal cancer treated with cetuximab.. Patients receiving first-line cetuximab + FOLFIRI were randomly assigned to prophylactic treatment with doxycylin and vitamin K1 cream or doxycycline and the vehicle. The primary end point of the study was the incidence of grade ≥ 2 skin rash (NCI CTCAE version 4.02) during 8 weeks of skin treatment. Secondary end points comprised skin rash according to a more thorough tripartite skin toxicity score (WoMo), quality of life, efficacy, and compliance. The study had 80% power to show a 20% reduction of the incidence of grade ≥ 2 skin rash.. A total of 126 patients were analyzed. The incidence of skin rash grade ≥ 2 was comparable between the arms. Likewise, no difference was seen in the WoMo score with respect to the percentage of skin affected. However, starting in week 5 and increasing over time patients treated with vitamin K1 cream had less severe rash and fewer fissures. Quality of life as well as efficacy and compliance with study medication and anticancer treatment was comparable in both arms.. The primary end point of decreasing grade ≥ 2 skin rash was not met. However, using vitamin K1 cream as part of prophylactic treatment decreased the severity of acne-like skin rash according to WoMo, an alternative and more thorough skin toxicity scoring tool.

Cetuximab-induced skin rash Gd3+ occurs in ≥16% patients (pts) (Heinemann et al., Lancet Oncol 15(10):1065-1075, 2014; Van Cutsem et al. J Clin Oncol 27(19):3117-25; 2009b). Survival, response, and toxicity parameters were re-evaluated under a pre-defined skin prophylaxis consistent of vitamin K1 ointment and oral doxycycline.. This is a national, multicenter, phase 4, first-line mCRC (K-RAS wt) trial. Pts received irinotecan 180 mg/m² (d1), FA 400 mg/m² (d1), 5-FU 400 mg/m² (d1), 5-FU 2400 mg/m² (d1-2), and cetuximab [400 mg/m² (d1), and then 250 mg/m² qw], prophylactic 0.1% vitamin K1 ointment qd, and oral doxycycline 100 mg bid.. 1-year PFS rate; secondary objectives: skin side-effects (grade, onset), objective response rate (ORR), disease control rate (DCR), progression-free survival (PFS) time, and overall survival (OS) time and safety.. Twenty centers recruited 55 patients. Recruitment started Q1 2011 and ended Q3 2013 due to slow accrual. Characteristics were in line with CRYSTAL trial except for age and colonic location. 1-year PFS rate was 25.9%, mOS 21.8 months (m), and mPFS 8.5 m. ORR was 63.0%, DCR 77.8%. Rash Gd2+ occurred in 42.6% [median onset was 4.0 weeks (w)]; paronychia Gd2+ occurred in 22.2% (median onset 15.4w.); skin fissures Gd2+ occurred in 31.5% (median onset 19.9 weeks) 7% pts abandoned cetuximab treatment due to toxicity.. Our data reveal encouraging improvements in skin reactions and their time to occurrence due to a pre-defined skin care.

Cetuximab is an effective option for the treatment of metastatic colorectal cancer in the first and subsequent lines of treatment; among its side effects, acneiform skin rash is one of the major causes of treatment delay, reduction, or interruption, with a negative effect on quality of life. No effective strategy to prevent skin rash induced by epidermal growth factor receptor inhibitors is available; however, encouraging results have come from vitamin K1, phytomenadione, applied as a topical formulation. Available studies have been conducted in heterogeneous populations and are mainly focused on the use of vitamin K1-based cream for the treatment, rather than the prophylaxis, of acneiform rash.. Forty-one consecutive patients from a single center all affected by metastatic colorectal cancer and receiving cetuximab, alone or combined with chemotherapy, applied vitamin K1-based cream to prevent the occurrence of acneiform skin rash. The cream was applied twice a day on the face and trunk from the first day of administration of cetuximab.. The application of the cream was well tolerated. No grade 4 rash was reported. The proportion of grade 3 skin rash in the first 8 weeks of treatment in this population was 15%, at the lower limit of values reported in the literature, and the proportion of patients with grade 2 rash was reduced (22.5%).. This experience confirms available data in a homogeneous population, suggesting a possible benefit of topical vitamin K1 as prophylaxis for cetuximab-induced skin rash in patients with metastatic colorectal cancer.

The study aimed to investigate strategies to prevent and treat cetuximab-induced skin reactions and their perceived effectiveness in patients with metastatic colorectal cancer (mCRC) and recurrent/metastatic squamous cell cancer of the head and neck (SCCHN).. This open-label, prospective observational study was conducted in Switzerland.. A total of 125 patients were included (n = 91 mCRC, n = 34 SCCHN; mean age 63.3 years; 73.6% males). The frequency of acneiform rash grade ≥ 2 increased from 12.6% at week 2 to 21.7% at week 16. The proportion of patients who reported no skin reaction decreased from 75.6% at week 2 to 43.3% at week 16. The most frequently used skin products at any time of observation were moisturizing (77.6%), lipid-regenerating (56.8%) or urea-containing products (52%), systemic antibiotics (49.6%), and vitamin K1 cream (43.2%). There was no clear effectiveness pattern for all product classes: in given patients, either the product showed no effect at all or a moderate/strong effect, consistently over time.. A great variety of low-cost general skin care products were commonly used. According to physician's preference, systemic antibiotics and vitamin K1 cream are an appropriate approach to prevent or treat cetuximab-related skin toxicity.

To discuss the impact of 0.1% vitamin K1 (VitK1) cream on cetuximab-induced skin toxicity for colorectal cancer patients. 60 colorectal cancer patients with cetuximab therapy after hospitalization, were divided into experimental group (Ward A) and control group (Ward B) according to personnel sequential number, with 30 cases in each group. Routine nursing was implemented on control group. For experimental group, on the routine nursing basis, 0.1% VitK1 cream was smeared on face, neck, chest, back and nail (toenail) edge with three times one day at the application of cetuximab day. After cetuximab applied in 8 weeks, both skin itch and dry skin for patients in experimental group were significantly improved compared those in control group, showing statistically significant difference (W=708.000, P=0.001: W=662. 500, P=0.000). 0.1% VitK1 cream was conducive to improve both skin itch and dry skin symptoms in the cetuximab-induced skin toxicity for colorectal cancer patients.

Targeted oncology therapy with inhibitors of epidermal growth factor receptor is associated with numerous cutaneous side effects. Acneiform eruptions are the most frequent skin toxicities reported. They may lead to impairment of patients' quality of life and sometimes may even become severe enough to necessitate the interruption or cessation of therapy.. To assess the possible effect of topical phytomenadione (vitamin K1 ) pre-treatment in diminishing the extent and severity of acne-like follicular rash associated with epidermal growth factor receptor inhibitor therapy.. A series of 20 patients with colorectal cancer or head and neck cancer were pre-treated with phytomenadione cream (0.05% in seven patients and 0.1% in 13 patients), starting morning before the first infusion of cetuximab or panitumumab, and followed up for the development of therapy-associated folliculitis. The cream was prepared from phytomenadione solution added to a hydrophilic cream base, oil in water, to obtain the concentration of 0.05% or 0.1%.. Majority of patients (15 out of 20, 75%) pre-treated with phytomenadione cream experienced only mild, grade I acneiform eruptions. Five patients (25%) had grade II rash, which included two of seven patients pre-treated with 0.05% phytomenadione cream and three of 13 patients who used 0.1% phytomenadione cream. Topical phytomenadione cream was well tolerated and no abnormalities in blood coagulation were observed.. Topical pre-treatment with phytomenadione cream might become useful in epidermal growth factor inhibitor-associated acneiform eruptions.
