RESUMEN
CONTEXT: Better locoregional control and increased overall survival by continuous hyper fractionated accelerated radiotherapy have been shown in unresectable nonsmall cell lung carcinoma (NSCLC). Dose escalation and neoadjuvant chemotherapy (NACT) along with continuous hyperfractionated accelerated radiotherapy week end-less (CHARTWEL) were also tried for improved survival. In this present study, we compared the results of NACT followed by CHARTWEL against NACT followed by conventional concurrent chemo-radiation therapy. AIMS: The aim of this study is to compare the locoregional control and toxicities in NSCLC Stage IIIA and B in both arms. SETTINGS AND DESIGN: Randomized, prospective single-institutional study with a study population comprising all locally advanced unresectable NSCLC patients enrolled in 2014 at our institute. SUBJECTS AND METHODS: All enrolled patients were randomized into two arms-CHARTWEL and concomitant chemo-radiotherapy (CCRT), after three weeks of the fourth cycle of NACT. In CHARTWEL arm 30 patients received two-dimensional radiotherapy (RT) 58.5 Gy/39 fr/2.5 weeks while in CCRT arm 30 received 66 Gy/33 fr/6.5 weeks. Disease response was evaluated at 6 months and toxicity assessment during and after treatment completion. Data were analyzed using tools such as percentage, mean, Chi-square test and P value. Chi-square and P value was calculated by statistical online software (http://quantpsy.org). RESULTS: 28% of patients in study arm and 20% in control arm had complete response at 6 months after RT. Locoregional disease control was observed in 44% in study arm and 32% in control arm of patients. There was no statistical difference in grades of toxicities or overall survival (OS)/disease-free survival except persistent esophagitis Grade III seen in two patients of study arm. CONCLUSIONS: Study suggests that CHARTWEL in combination with NACT is an effective strategy to treat patients with locally advanced lung cancer with the advantage of a smaller dose and shorter duration. Although large multivariate studies still needed.

The radiation recall dermatitis (RRD) phenomenon is defined as the "recalling" of the skin following the administration of drugs; this induces a response or flare-like reaction over the skin that is exposed to radiation. In this case report, a young female developed RRD on Day 18 after the completion of cranial radiotherapy, that is, four days after the restart of the chemotherapy with doxorubicin. It is a self-limiting condition with supportive care as the treatment. When encountered in hematological malignancies, undue treatment breaks can delay definitive treatment and can eventually cause a relapse.
RESUMEN
AIM: The data of survival for Indian cervical cancer patients treated by indigenous modifications of the protocol are scarce. The objective of this retrospective study was to analyze the efficacy and tolerability in patients of cervical carcinoma treated by neoadjuvant chemotherapy followed by concurrent chemoradiation. MATERIALS AND METHODS: Three hundred and thirty two cases of squamous cell carcinoma of cervix who received 3 cycles of neoadjuvant chemotherapy followed concurrent chemoradiation were retrospectively analyzed for overall survival (OS), disease-free survival (DFS), and local pelvic control rate. RESULTS: The 3-year OS and DFS were 93.7 % for stage I-B, 88.0 and 84.0 % for stage II-A, 82.8 and 79.7 % for stage II-B, 70.0 and 64.9 % for stage III-A, 59.3 and 52.4 % for stage III-B, and 53.6 and 32.1 % for stage IV-A disease. The 5-year OS and DFS rates were 93.7 and 87.5 % for stage I-B, 84.0 % for Stage II-A, 79.7 and 76.6 % for stage II-B, 67.6 and 59.5 % for stage III-A, 48.4 and 41.9 % for stage III-B, and 28.6 and 14.3 % for stage IV-A disease. CONCLUSION: Neoadjuvant chemotherapy followed by concurrent chemoradiation is feasible and produces impressive disease-free and overall survival. This protocol is especially helpful for busy cancer centers with long waiting lists on radiotherapy machines.
