RESUMEN

Assess the interfraction dose variations of the organs at risk (OARs) in carcinoma cervix high dose rate (HDR) computed tomography (CT)-guided intra cavitary brachytherapy (ICBT). 120 CT scans of 40 patients who had undergone three fractions of ICBT (7 Gy/fr) were analyzed. Dose to Point A and the minimum doses to the volumes of 2, 1, and 0.1cc of bladder, rectum and sigmoid colon were recorded. Revised plans were generated in 20 patients. Paired t-test was used to compare the difference in the means. Point "A" mean dose difference was statistically significant between the treated and revised plans. For bladder, the difference in means of dosage to all volumes, whilst for the rectum and sigmoid colon, the low volume dosage (0.1cc) was statistically significant. Absence of individualized planning would have resulted in underdosage of tumor and increased dosage of up to 30% to OARs. CT-guided ICBT should be implemented for each HDR fraction treatment.

RESUMEN

Ewing's sarcoma (ES)/peripheral primitive neuroectodermal tumors usually arise in the long bones of children and young adults. Primary ES of the cranium is unusual. Treatment involves multi-modality therapy incorporating surgery, radiotherapy and chemotherapy; outcomes are similar to those arising from long bones. We report a case of Primary ES of the squamous part of temporal bone with intracranial extension in a 9-year-old girl who was treated with surgery, chemotherapy followed by adjuvant radiotherapy by volumetric arc therapy. Post 1-year of treatment the girl is performing well in her classes.

RESUMEN

Coexistence of tuberculosis (TB) in the breast or axillary lymph nodes with breast carcinoma though rare is not unknown. A 55-year-old woman presented with right axillary and left supraclavicular lymphadenopathies with no detectable lesion in either breasts or left axilla. Right axillary lymph node excision biopsy revealed metastatic adenocarcinoma. Diagnostic workup showed intense fluorodeoxyglucose (FDG)-avid lymph nodes on the left side neck at level V, supraclavicular, axillary, subpectoral and para-aortic regions, and low FDG activity in the right breast. Core biopsy of right breast lesion was reported as invasive ductal carcinoma and cytology of multiple left axillary lymphadenopathies as reactive hyperplasia. Excision biopsy of the supraclavicular lymph nodes unveiled the diagnosis of TB. She underwent right-modified radical mastectomy followed by external beam radiotherapy, has completed antituberculous treatment and is on follow-up. Extrapulmonary TB though uncommon; may be found in certain cases. Clinicians must be aware of its existence.

RESUMEN

BACKGROUND: The standard radiotherapy (RT) fractionation practiced in India and worldwide is 50 Gy in 25 fractions over 5 weeks to the chest wall or whole breast followed by tumour bed boost in case of breast conservation (BCS). A body of validated data exists regarding hypofractionation in breast cancer. We here report initial results for 135 patients treated at our center with the START-B type of fractionation. MATERIALS AND METHODS: From May 2011 till July 2012, women with all stages of breast cancer (excluding metastatic), who had undergone BCS or mastectomy were planned for 40 Gy in 15 fractions over 3 weeks to chest wall/whole breast and supraclavicular fossa (where indicated) followed by tumour bed boost in BCS patients. Planning was done using Casebow's technique. The primary end point was to assess the acute toxicity and the cosmetic outcomes. Using cosmetic scales; patients were assessed during radiotherapy and at subsequent follow up visits with the radiation oncologist. RESULTS: Of the 135 patients, 62 had undergone BCS and 73 mastectomy. Median age of the population was 52 years. Some 80% were T1 and T2 tumours in BCS whereas most patients in mastectomy group were T3 and T4 tumours (60%). 45% were node negative in BCS group whilst it was 23% in the mastectomy group. Average NPI scores were 3.9 and 4.9, respectively. Most frequently reported histopathology report was infiltrating ductal carcinoma (87%), grade III being most common (58%), and 69% were ER positive tumours, and 30% were Her 2 Neu positive. Triple negative tumours accounted for 13% and their mean age was young (43 yrs.) The maximum acute skin toxicity at the end of treatment was Grade 1 in 94% of the mastectomy group patients and 71% in BCS patients. Grade 2 toxicity was 6% in mast group and 23% in BCS group. Grade 3 was 6% in BCS group, no grade 3 toxicity in mastectomy patients and there was no grade 4 skin toxicity in any case. Post RT at 1 month; 39% of BCS patients had persisting Grade I skin reaction which was only 2% in mastectomy patients. At 3 months post RT, 18% patients had persisting hyperpigmentation. At 6 months 8% patients had persisting erythema in the BCS group only. Some 3% BCS and 8% mastectomy patients had lymph edema till the date of evaluation. Cosmetic outcome in BCS patients remained good to excellent 6 months post surgery and radiotherapy. 1 patient of BCS and 3 patients of mast had developed metastatic disease at the time of evaluation. CONCLUSIONS: Hypofractionated RT is well tolerated in Indian population with reduced acute skin toxicity and good cosmetic outcome. Regimens such as these should be encouraged in other centers to increase machine output time. The study is on-going to assess long term results.

RESUMEN

BACKGROUND: A retrospective analysis of all cancer patients attending the radiotherapy outpatient department (OPD) of a single unit during the period of January 2005 till December 2006 was conducted to know the geographical distribution and incidence of the most common cancers, their stage of presentation, treatment compliance among the patients and follow-up. MATERIALS AND METHODS: A total of 4,484 patients were registered in the Institute of Medical Sciences, Banaras Hindu University during the period of January 2005- December 2006; of which 1,975 registered in an individual unit were included for the retrospective analysis. RESULTS: Most of the patients hailed from the various districts of UP and Bihar. Females outnumbered males with a ratio of 1.33:1. Females mostly belonged to the age group of 40-59 years; whilst males were a decade older. Major cancer sites in females were cervix and breast followed by head and neck. Leading cancer sites in males were head and neck, brain, bone, soft tissue and lung. Most of the cases presented in advanced stage of disease (74%). Squamous cell carcinoma was the most common histopathology (56%). A significant proportion of patients defaulted after undergoing preliminary investigations (16%). Only 53.9% of females and 58.5% of males took treatment out of which 68% and 63% completed the prescribed treatment. Compliance with follow-up was poor. CONCLUSIONS: The outcome of this study will significantly help us to define region specific strategies needed for cancer management in eastern Uttar Pradesh.
