Lung cancer occurred in approximately 1,8 million patients and caused an estimated 1,6 million deaths in 2012, worldwide. NSCLC constitutes approximately 85% of all lung cancers. Patients with early-stage NSCLC are surgically treated for curative goals. However, many patients are at risk of recurrence despite complete resection. This suggests that a large proportion of patients have the micrometastatic disease even at the early course of the disease. In this review, we aimed to evaluate the results of adjuvant chemotherapy, targeted therapy and immunotherapy studies to improve survival in NSCLC.

The study aims to evaluate the vismodegib treatment in local advanced (laBCC) and metastatic (mBCC) basal cell carcinoma. The data of 29 patients were retrospectively reviewed. The clinical and histopathological features of the patients and adverse events of vismodegib were recorded. Overall survival (OS) and progression-free survival (PFS) were evaluated with Kaplan-Meier analysis. The median follow-up period was 17 months (range: 1.6-57.3), and the median age at diagnosis 73 years (range: 39-88). The most common disease location was head and neck (86.2%), and the most common non-skin sites of disease were lymph nodes (13.8%), bone (13.8%), lung (6.9%), and brain (6.9%). Three (10.3%) patients had Gorlin's syndrome. The number of metastatic patients was 5 (17.2%). With vismodegib treatment, the complete response rate was 27.6%, partial response 55.2%, and stable response 10.3%. Treatment responses were most frequently seen within 2 months from the beginning of vismodegib. The median OS was 43.3 ± 9.0 months (25.6-61.1) for all patients. The median PFS in the laBCC was 15.7 ± 1.8 months (12.2-19.3), and 12.1 ± 4.6 months (2.9-21.2) in the mBCC. In the univariable analysis for the OS, only the treatment after the vismodegib was statistically significant, showing chemotherapy was better comparing to no treatment or surgery. The most common adverse events were fatigue-58.6%, muscle spasms-48.3%, alopecia-13.8%, and weight loss-13.8%. This real-life data study shows that vismodegib treatment in locally advanced and metastatic BCC was well tolerated and effective.

Purpose: Taxane-containing combinations are recommended for the first-line therapy of advanced gastric cancer. It is not known which chemotherapy regimen is the best with trastuzumab for HER2-positive patients. The aim of this study was to compare taxane-containing intensified chemotherapy versus standard chemotherapy in combination with trastuzumab in the first-line treatment of HER2-positive advanced gastric adenocarcinoma. Methods: This study is a retrospective multicenter study of the Turkish Oncology Group. A total of 130 HER2-positive patients with inoperable locally advanced, recurrent, or metastatic gastric adenocarcinoma being given chemotherapy plus trastuzumab as the first-line treatment were included from 16 different oncology centers. Trastuzumab combination with intensified chemotherapy including taxane or standard chemotherapy was compared in terms of progression-free survival (PFS), overall survival (OS), and toxicity. Results: There were 108 patients in the standard and 22 patients in the intensified chemotherapy group. PFS of the standard and intensified group were 5.6 months (95% confidence interval [CI] 4.8–6.4) and 5.3 months (95% CI 2.6–8), respectively ( p = 0.70). OS of the standard and intensified group were 11.1 months (95% CI 8.3–13.9) and 15.2 months (95% CI 12.7–17.7), respectively ( p = 0.03). Repeated analysis excluding patients given any previous therapy revealed similar results. The intensified group had more fever and febrile neutropenia. Conclusion: Trastuzumab combination with intensified chemotherapy provides better OS in first-line treatment of HER2-positive advanced gastric cancer. Further large-scale studies should be performed in HER2-positive patients.

Introduction Colorectal cancer is one of the most common cancers in the world. Cetuximab is an epidermal growth factor receptor (EGFR) inhibitor which provides survival benefit when combined with chemotherapy in RAS wild type metastatic colorectal cancer. Cutaneous toxicities associated with cetuximab have a significant impact on patient quality of life, treatment continuation and healthcare resource utilization. Case report A 60-year-old male patient presented with fatigue, weight loss and abdominal pain. Two closely located malignant polypoid lesions were detected in the sigmoid colon, and pathological examination revealed colonic adenocarcinoma. Management and outcome: Thorax, abdominal and pelvic computed tomography showed metastases. FOLFOX chemotherapy and cetuximab were started. The patient developed acneiform rash firstly in his face, although prophylactic vitamin K1 0.1% containing cream was given. He was given mild potency topical corticosteroid and doxycycline. The lesions progressed to his front and back body. He did not want to use topical vitamin K1 cream, topical steroid and doxycycline tablets. Instead, he wanted to use aloe vera extract which he produced from the leaves of the plant. Patient’s lesions were regressed significantly. Discussion The most common and earliest skin toxicity is acneiform rash which affects 60 to 80% of the patients. In this case, cetuximab-related severe acneiform rash was effectively treated by topical aloe vera. Topical aloe vera may be used in the management of cetuximab-related cutaneous toxicities without any side effect.
