Sunitinib is a vascular endothelial growth factor receptor inhibitor which has shown high activity in metastatic renal cell carcinoma (mRCC) patients and is now widely used for the same. It is generally well tolerated, but sometimes, it exhibits a distinct pattern of novel side effects that require monitoring and management. Important known side effect of sunitinib includes fatigue, diarrhea, anorexia, skin toxicity, and hypertension which need special mention. Considering its effectiveness in first-line setting in mRCC and paucity of other good options, utmost efforts are made to continue it with identification of side effects which may require only slight dose modification or no dose alteration. We report here a 38-year-old male who was diagnosed as a case of mRCC and started on sunitinib at the diagnosis and developed whitish discoloration of eyebrows and body hairs after 3 months of starting sunitinib. In view of good overall response to treatment and no other significant toxicity, sunitinib was continued with good tolerability.
e16526 Background: Neo-adjuvant chemotherapy followed by surgery is the standard of care in non metastatic oesophageal cancers. After the overall survival benefit observed in Cross trial, Paclitaxel and Carboplatin based neo-adjuvant chemoradiation has become the preferred treatment modality. There is paucity of data of its efficacy and tolerability in Indian patients. So this prospective study was done to assess the same. Methods: We enrolled 64 patients aged 18-75 years with histologically confirmed, potentially resectable squamous-cell carcinoma of the esophagus or esophagogastric junction from Aug 2017 to Jan 2019. On days 1, 8, 15, 22, and 29, carboplatin AUC 2 and paclitaxel 50 mg/m2 intravenously and a total radiation dose of 41.4 Gy was given in 23 fractions of 1.8 Gy each by external-beam radiation. Pathological complete response rate, Clinical response based on PET-CT scan and tolerability of paclitaxel and carboplatin as a concurrent chemotherapeutic radiation sensitizer regimen was studied. Results: 23 out 64 patients underwent surgery while others were either lost to follow up or they refused for surgery. Of these 23, 87.5% could complete all 5 planned cycles of chemotherapy. Complete pathological response was found in 73.9% patients. Statistically significant correlation was found between pathological and PET-CT based response (p-0.044). 4 patients showed distant progression on PET-CT based evaluation after neoadjuvant chemo radiotherapy before surgery. The most common major hematologic toxic effects were leukopenia (14%) and neutropenia (12.5%). Febrile neutropenia and grade 3 anemia was observed 2 and 4 patients respectively. The most common major non-hematologic toxic effects were vomiting (4.6%), nausea (3.1%), bronchoesophageal fistula(3.1%). Post operative mortality was seen in 1(4.3%) patient. Grade 3 pulmonary complications, atrial fibrillation and anastomotic leak was observed in 1 patient each. Conclusions: Concurrent chemoradiotherpy with weekly paclitaxel and caboplatin is well tolerated in Indian patients. High complete resection rate and PCR rate can be achieved with this regime with manageable adverse effect profile. Response evaluation with PET-CT after completion of preoperative therapy has correlation with pathological complete response.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
