RESUMO

BACKGROUND: Before the approval of first-line immune checkpoint inhibitors, platinum doublets were the standard of care in patients with treatment-naïve advanced non-small cell lung cancer (NSCLC) without targetable driver mutations. Pemetrexed-platinum combinations are preferred in non-squamous NSCLC. However, there has been no direct comparison to paclitaxel-carboplatin. METHODS: This open-label randomized trial was designed to compare pemetrexed-carboplatin with (weekly) paclitaxel-carboplatin in treatment-naïve advanced/metastatic non-squamous NSCLC without driver mutations. Patients received either pemetrexed 500 mg/m2 and carboplatin AUC 5 every 3 weeks, or paclitaxel 80 mg/m2 on day 1, day 8, and day 15 with carboplatin AUC 5 every 4 weeks for 4 cycles. Patients in both arms were allowed to receive pemetrexed maintenance. RESULTS: A total of 180 patients were enrolled. The study was terminated early; however, at the time of analysis 75.8% of the required events had occurred. Finally, 164 patients were evaluable, 83 in the pemetrexed arm and 81 in the paclitaxel arm. After a median follow-up of 17 months, progression-free survival (PFS) rates at 6 months were not different in the two treatment arms (47.45 vs. 48.64%, p = 0.88). The median PFS values were 5.67 months (95% CI 3.73-7.3) and 5.03 months (95% CI 2.63-7.43) in each arm, respectively (HR 1.13, 95% CI 0.81-1.59, p = 0.44). The median overall survival was also not different: 14.83 months (95% CI 9.5-18.73) and 11.3 (95% CI 8.3-19.7; HR 1.19, 95% CI 0.8-1.78, p = 0.37). All grade toxicities were similar except for alopecia and peripheral neuropathy, which were higher in the paclitaxel arm. CONCLUSION: Pemetrexed-carboplatin is not superior to (weekly) paclitaxel-carboplatin as the first-line regimen in advanced non-squamous NSCLC in terms of PFS.

RESUMO

BACKGROUND: No data exist for the long-term outcome of metastatic colorectal cancer (mCRC) from the Southern part of Asia. The primary objective of the study is to evaluate the survival outcome of mCRC from an Indian tertiary care center. The study also aims to highlight the treatment pattern practiced and the unique clinico-pathologic characteristics. METHODS: This is a single-center retrospective observational study done at a large referral tertiary care center in North India. All patients with synchronous or metachronous mCRC who received at least one dose of chemotherapy for metastatic disease, registered between 2003 to 2017 were included. Primary outcome measures were overall survival and progression-free survival and prognostic factors of overall survival. Descriptive analysis was done for the clinicopathological characteristics and treatment patterns. Kaplan Meier method for overall survival and progression-free survival. Cox regression analysis was performed for the determination of the prognostic factors for overall survival. RESULT: Out of 377 eligible patients, 256 patients (68%) had de novo metastatic disease and the remaining 121 (32%) progressed to metastatic disease after initial treatment. The cohort was young (median age, 46 years) with the most common primary site being the rectum. A higher proportion of signet (9%) and mucinous histology (24%). The three common sites of metastasis were the liver, peritoneum, and lung. In the first line, most patients received oxaliplatin-based chemotherapy (70%). Only 12.5% of patients received biologicals in the first-line setting. The median follow-up and median overall survival of study cohort were 17 months and 18.5 months. The factors associated with poor outcome for overall survival on multivariate analysis were ECOG performance status of > 1, high CEA, low albumin, and the number of lines of chemotherapy received (< 2). CONCLUSION: The outcome of mCRC is inferior to the published literature. We found a relatively higher proportion of patients with the following characteristics; younger, rectum as primary tumor location, the signet, and mucinous histology, higher incidence of peritoneum involvement. The routine use of targeted therapies is limited. Government schemes (inclusion of targeted therapies in the Ayushman scheme), NGO assistance, and availability of generic low-cost targeted drugs may increase the availability.

RESUMO

Background: . Tumours of the eyelid are a rare subgroup of neoplasms with varied histology and inherent differences in clinical behaviour. Surgery is the standard of care, and adjuvant radiation therapy (RT) is given in the presence of features suggesting a high risk of local recurrence. The treatment of lymph nodes in the neck is debatable. We reviewed the utility of RT for lymph nodes in the neck in patients with malignant tumours of the eyelid. Methods: . We reviewed medical records of all patients with tumours of the eyelid treated at our centre from July 2006 to December 2014 for their demographic, clinical profile, treatment details and outcome. Results: . The records of 37 patients were included for analysis, of these 34 underwent surgery and 21 received adjuvant RT. Their median age was 60 (range 30-85) years. Sebaceous cell carcinoma was the most common (50.4%). The median disease-free survival (DFS) was 35 months (95% CI 17.9-52.0). The 1- and 3-year DFS were 82.7% and 45%, respectively. Univariate analysis showed a superior outcome with early stage (T1) tumours (p=0.01), RT dose of ≥60 Gy and those underwent lymph node dissection (p=0.03). The presence of high-risk factors including close or positive margin had an inferior outcome with a trend towards statistical significance (p=0.06). Conclusion: . We found a favourable outcome with early T stage, RT dose of ≥60 Gy and lymph node dissection. High-risk histopathological features including close margins and positive lymph nodes merit adjuvant RT including regional lymph nodes.

RESUMO

The study was aimed at evaluating adherence to treatment protocol and outcome in pediatric parameningeal rhabdomyosarcoma (PM-RMS). We analyzed the characteristics, treatment administered, outcomes and patterns of failure of pediatric PM-RMS, who were treated with multimodality therapy between January 2005 and December 2013.Univariate and multivariate analysis (MVA) was completed to evaluate the impact of various prognostic factors. Thirty-seven patients were treated at our institution. Majority of them had the primary disease in paranasal sinuses (n=13). Majority of the patients belonged to group III (n=30) and stage III (n=24). The overall response rate to treatment was 52.5% (n=21). At a mean follow-up of 19.1 months, 23 patients developed disease progression. The actuarial rates of failure-free survival and overall survival (OS) at 2 years were 40% and 67.5%, respectively. Patients who received >20 weeks of intended chemotherapy schedule (P=0.02) and had complete response to first-line treatment (P=0.0004) were found to have superior failure-free survival on MVA. Complete response was the lone determinant of superior OS on MVA (P=0.006). Majority of patients with PM-RMS present with advanced stage disease. Response to first-line treatment is a significant predictor of superior progression-free survival and OS in these patients.

RESUMO

PURPOSE: To compare the efficacy of 2 chemotherapeutic drug combinations as part of multimodal therapy for orbital retinoblastoma. DESIGN: Prospective, comparative, study. PARTICIPANTS: Patients with stage III retinoblastoma (International Retinoblastoma Staging System). METHODS: Demographic and clinical features were recorded at presentation. Treatment consisted of a multimodal protocol with neoadjuvant chemotherapy, enucleation, orbital external-beam radiotherapy, and adjuvant chemotherapy. For chemotherapy, patients were randomized into 2 groups: group A patients were treated with vincristine, etoposide, and carboplatin (VEC) and group B patients were treated with carboplatin and etoposide, alternating with cyclophosphamide, idarubicin, and vincristine. Treatment outcomes and adverse effects were recorded. Efficacy parameters were compared between the groups. MAIN OUTCOME MEASURES: Survival probability, cause of death, and chemotherapy-related toxicity. RESULTS: A total of 54 children were recruited (27 in each group). The mean ± SD follow-up was 21.3±11.34 months. The overall Kaplan-Meier survival probability was 80% (95% confidence interval [CI], 0.67-0.89) and 42% (95% CI, 0.24-0.59) at 1 year and 4 years, respectively. There were 9 deaths in group A and 15 deaths in group B. The Kaplan-Meier survival probability at 1 year was similar between the groups: 81% (95% CI, 0.60-0.91) and 79% (95% CI, 0.58-0.9) for groups A and B, respectively. At 4 years, the survival probability for group A was higher (63% [95% CI, 0.41-0.79] vs. 25% [95% CI, 0.08-0.46] for groups A and B, respectively), with a strong trend of better survival in group A over time (P = 0.05). The major cause of death was central nervous system relapse (8 patients in group A and 7 patients in group B). Two patients in group B died of sepsis after febrile neutropenia. Grade 3 and grade 4 hematologic toxicities were more common in group B, with a significant difference in grade 4 neutropenia (P = 0.002). CONCLUSIONS: This study compared the outcomes of VEC chemotherapy with a 5-drug combination of etoposide and carboplatin, alternating with cyclophosphamide, idarubicin, and vincristine, for stage III retinoblastoma. The VEC combination was found to be more effective and may be recommended as neoadjuvant and adjuvant chemotherapy.

RESUMO

BACKGROUND & OBJECTIVES: Studies have shown that immunohistochemical (IHC) staining using epidermal growth factor receptor (EGFR) mutation specific antibodies, is an easy and cost-effective, screening method compared with molecular techniques. The purpose of present study was to assess the percentage positivity of IHC using EGFR mutation specific antibodies in lung biopsy samples from patients with primary lung adenocarcinoma (ADC). METHODS: Two hundred and six biopsies of primary lung ADC were subjected to EGFR mutation specific antibodies against del E746-A750 and L858R. Detection of EGFR mutation done by high resolution melting analysis (HRM) was used as gold standard. A concordance was established between molecular and IHC results. Frequency of IHC positivity was assessed. RESULTS: Of the 206 patients, 129 were male and 77 were female patients, with a mean age of 54.1 yr. Fifty five (26.6%) patients (36 men; 19 women) showed positivity for IHC of del E746-A750 (33) and L858R (22). HRM results were available in 14 patients which showed EGFR mutations in correspondence with del E746-750 or L858R in 64.2 per cent cases. Positive cases on HRM were further confirmed by DNA sequencing and fragment analysis. Three patients showed exon[20] variation. Two cases were negative for mutation. The genotype of del E746-750 mutation was more common than L858R. A concordance was established between molecular mutation and IHC in 85.7 per cent cases. INTERPRETATION & CONCLUSIONS: In this preliminary study from India mutation specific IHC was used for assessment of mutation status of EGFR. Although the number tested was small, a good concordance was observed between molecular EGFR mutation and IHC expression. IHC methodology is a potentially useful tool to guide clinicians for personalized treatment in lung ADC, especially where facilities for molecular analysis are not readily available and for use in small biopsies where material is scant for molecular tests.

RESUMO

A 55-year-old woman presented with a complaint of post-menopausal bleeding per vaginum. Local examination revealed a mass, protruding from the cervical os, which detached spontaneously. An adnexal mass was felt through the pouch of Douglas on per vaginum examination. Histopathological examination of the avulsed specimen revealed a diagnosis of malignant mixed Müllerian tumor. The patient underwent surgical staging with total abdominal hysterectomy, bilateral salpingo-oophorectomy, left pelvic lymphadenectomy, infracolic omentectomy, and peritoneal wash cytology. Pathological examination revealed a second primary tumor, that is, a transitional cell carcinoma of the ovary. Both the uterine malignant mixed Müllerian tumor and the ovarian transitional cell carcinoma were staged as IA. Subsequently, the patient was treated with adjuvant chemotherapy followed by radiotherapy. The patient is in complete remission at 1 year following the treatment. Synchronous genital tract neoplasms constitute a therapeutic challenge and necessitate an effective multimodality therapeutic approach based on meticulous pathological examination and tumor staging.

RESUMO

BACKGROUND: Gastrointestinal stromal tumors (GIST) are the most common mesenchymal tumors of the gastrointestinal tract. We aimed to study the pattern of presentation and treatment outcome of advanced GIST patients seen by us in a 10- year period. METHODS: Medical records of GIST patients seen between years 2002-2012 were retrieved from institute as well as database maintained by authors. Patient included in this analysis had metastatic disease and unresectable and/or residual disease after surgery. RESULTS: During the study period 62 patients fulfilled the inclusion criteria but 6 were lost to follow up before treatment and hence 56 patients were analysed. Median age was 45.5 years (range 17-70 years) with a male female ratio of 2:1. Thirty eight (67%) patients had metastatic disease whereas 32% patients had unresectable or incompletely resected disease. The most common primary site was small intestine in 24 (42.8%) which was followed by stomach in 11 (19.6%) patients. The most common site of metastases was liver in 27 (48%) patients. Median tumor size was 12 cm (range 4-50 cm). Thirty two (57%) patients had mitotic counts of > 5/50 HPF. All patients received imatinib. The most common response seen with imatinib was stable disease achieved in 29 (52%) patients. Imatinib was well tolerated by all patients without any drug discontinuation. The 5-year EFS and OS were 35% and 49%, respectively at a median follow up of 55 months. None of the patient or tumor factors were found to have prognostic significance in univariate survival analysis. CONCLUSIONS: This is a single center experience of advanced GIST patients where small intestine was found to be the commonest disease site with imatinib producing disease stabilization in more than half of patients. Even though the survival was comparable to published reports, the major limitation was lack of mutation analysis.

RESUMO

Introduction: Eyelid sebaceous gland carcinoma (SGC) is an aggressive malignancy. Surgical excision is the standard treatment for non-metastatic eyelid SGC. This study aimed to evaluate treatment outcomes with use of neoadjuvant chemotherapy (NACT) and any change in ease/difficulty of surgical treatment in such cases. Methods: This was a prospective interventional study conducted over 24-month period. Histopathologically, confirmed cases without any systemic metastasis were included. Clinico-demographic details were collected for 30 patients. 10 patients received NACT using cisplatin and 5-FU. Tumour response was evaluated using RECIST criteria. An ease of surgery questionnaire was used to assess difficulty of surgical treatment before and after NACT. Results: Of the 30 patients evaluated for recruitment, 37% had recurrent SGC and 72% had advanced tumour stage. Ten patients were recruited for NACT. There was partial response in 80% and complete response in 10% cases. Tumour T category downstaging was seen in 50% of cases. While tumour dimensions/volume reduced substantially, surgical ease improved in only 40% cases. Conclusion: A significant proportion of SGC patients evaluated in our study presented with recurrent and/or advanced disease. NACT caused tumour regression in 90% of cases. However, surgical ease improvement was limited, pointing to a need for surgical modification in such cases. Corneal ulceration was noted in 2 cases with large tumours causing a complete mechanical ptosis. Overall, the study introduced an ease of surgery questionnaire and provided insights into benefits and challenges of using NACT for eyelid SGC management.

RESUMO

OBJECTIVE: To evaluate role of dose dense neo-adjuvant chemotherapy (NACT) prior to standard concurrent chemo-radiation (CCRT) in locally advanced cervical cancer. METHODS: Between June 2010 and December 2011, 28 patients (median age - 51 years, range, 35 to 67 years) with locally advanced cervical cancer received NACT using paclitaxel (60 mg/m(2)) and carboplatin (AUC-2) weekly for 6 doses. After a mean interval of 15 days (range 7-23 days), the patients then received definitive radiation and concomitant weekly infusion of cisplatin (40 mg/m(2) for 6 doses). Response to concurrent chemo-radiation and toxicity were end points. RESULTS: Following NACT, 67.8% of patients responded; complete (CR) - 2(7.1%), Partial (PR) - 17 (60.7%), stable 7 (25.0%) and 2 patients (7.1%) progressed. 24 of 28 patients received CCRT; 23/24 achieved CR. 22 of 23 complete responders continue to be in CR at a median follow-up of 12 months (range, 7 to 24 months). Grade III/IV neutropenia was the main hematological toxicity seen in 28.5% and 29% of patients, respectively during NACT and CCRT. CONCLUSIONS: Neoadjuvant chemotherapy with dose dense weekly paclitaxel and carboplatin followed by standard CCRT is a feasible approach and is associated with a high response rate in locally advanced cervical cancer.

RESUMO

Data on prognostic factors in pelvic PNET are minimal. We analyzed patients with pelvic PNET treated between June 2003 and November 2011 for prognostic factors. Forty-eight (13%) of 374 patients with PNET were pelvic PNET with median age 14.5 years (range: 5-33); 31 (65%) had metastases. After median follow-up of 20.4 months (range: 1.3-64.9), 3-year EFS, OS, and local-control-rate were 13.5 ± 5.5%, 15.4 ± 9%, and 41.3 ± 14.9%, respectively. Hypoalbuminemia (≤3.4 g/dl) predicted inferior EFS and OS for both entire cohort and metastatic group. All patients with hypoalbuminemia (n = 10) had low BMI as compared to 23/38 without hypoalbuminemia (P = 0.02).

RESUMO

BACKGROUND: Management of locally advanced rectal cancer (LARC) is evolving with current emphasis on the addition of chemotherapy to short course radiotherapy (SCRT). We primarily aimed to analyse the difference in overall response rates between SCRT with sequential chemotherapy and standard long-course chemoradiotherapy (LCCRT)in LARC. METHODS: After randomization, patients in arm A received 45 Gy in 25 fractions over 5 weeks with concurrent capecitabine while patients in arm B received 25 Gy in 5 fractions over 1 week followed by 3 cycles of CAPOX (capecitabine and oxaliplatin) chemotherapy. Clinical and radiological response assessment was made after the completion of neoadjuvant treatment, a week prior to surgery. Adjuvant chemotherapy was added to complete 6 months of peri-operative chemotherapy. Surgery was performed between 8 and 10 weeks of completion of radiation treatment in both arms. RESULTS: Of the 33 patients recruited in this study between February 2020 to July 2021, 17 patients were randomized to arm A and 16 to arm B. The rates of complete tumour regression were 23.1% in arm A versus 35.7% in arm B (p-value = 0.683). Pathological complete response (pCR) rate was 20% arm A versus 30% in arm B (0.446). A higher number of patients in arm B experienced grade 3 diarrhoea, whereas acute skin toxicity was seen only in arm A. SCRT had fewer treatment interruptions compared to LCCRT. CONCLUSIONS: SCRT followed by three cycles of CAPOX chemotherapy in the neoadjuvant setting is comparable to LCCRT in terms of tumour response. This may be a better alternative regimen with fewer treatment interruptions in a resource-limited setting.

RESUMO

PURPOSE: This phase II trial is designed to test whether the performance status (PS) of metastatic non-small cell lung cancer (mNSCLC) patients (pts) can improve with chemotherapy if their poor PS (Eastern Cooperative Oncology Group (ECOG) PS of ≥ 2) is due to disease burden rather than comorbidities. METHODS: Age18-65 years, Charlson's comorbidity index < 9, serum albumin ≥ 3.5 g/dl, adequate bone marrow and organ function, & ECOG PS ≥ 2 as judged by the worst score of three independent physicians were administered 3 doses of weekly paclitaxel at 60 mg/m2/dose. The primary endpoint was an improvement in ECOG PS by 1 point at 4 weeks; others: toxicity (CTCAE v 5.0), quality of life (QoL) assessment at baseline and 4 weeks by EORTC QLQ-C30 and EORTC QLQ-LC13. Optimal Simon's 2-stage design was used. RESULTS:  Forty-six patients were included with a median age of 56 years (interquartile range, IQR 54-59), 12 (26%) had comorbid conditions, and 87% with ECOG PS 3/4. PS improved in 11 pts at 4 weeks and in 7 beyond this time point. Grade 3/4 toxicities are seen in 20% (most common: anemia and diarrhea). At a median follow-up of 4.8 m (95% CI 3.27-14.9), the median progression-free survival and overall survival were 3.3 months (95% CI 2.36-5.6) and 6.8 months (95% CI 2.47-8.8), respectively. QoL improved for global QoL, role functioning, pain, dyspnea, insomnia, pain in the chest, pain in other parts, and worsened for alopecia and sore mouth. CONCLUSIONS:  Abbreviated chemotherapy is a useful, well-tolerated strategy in carefully selected poor PS mNSCLC patients that can improve PS and QoL. CLINICAL TRIAL: Clinical trial information: CTRI/2020/01/022617.

RESUMO

PURPOSE: The present study prospectively evaluated outcome, pathologic findings, and compliance in orbital retinoblastoma patients (International Retinoblastoma Staging System [IRSS] stage III). DESIGN: Prospective study and case series. PARTICIPANTS: Twenty-eight consecutive IRSS stage III retinoblastoma patients were enrolled prospectively in the study after ethics committee approval and written informed consent. METHODS: Planned therapy for patients included treatment with a uniform protocol consisting of neoadjuvant chemotherapy followed by enucleation, adjuvant radiotherapy, and chemotherapy. Prospective computerized data entry and telephone contact were undertaken to improve compliance, a major issue in treatment of orbital retinoblastoma. MAIN OUTCOME MEASURES: Event-free survival (EFS) and overall survival (OS) were calculated using Kaplan-Meier survival analysis. The difference between groups was analyzed using the log-rank test. RESULTS: Median follow-up was 14.75 months (range, 2.23-26.3 months). The OS for all patients was 40.4% and the EFS was 33.33% at a follow-up of 26.3 months. The median EFS and OS were 10.37 months and 15.73 months, respectively. At baseline, bilateral retinoblastoma predicted inferior EFS (P = 0.0006) and OS (P = 0.0081). Twenty-two of 28 patients underwent enucleation, and viable tumor was present in 21 of 22 enucleated specimens (95%). Neoadjuvant chemotherapy prevented orbital exenterations. Presence of tumor in the cut end of the optic nerve significantly correlated with inferior EFS (P = 0.012) and OS (P = 0.0098). Central nervous system metastasis was the most common site of relapse and death. The overall rate of compliance with treatment was 67.8% (19/28), which was twice the compliance rate at the authors' center before initiation of the present study. CONCLUSIONS: There is a paucity of information in the literature on outcomes and pathologic findings after neoadjuvant chemotherapy in IRSS stage III retinoblastoma treated with a uniform treatment protocol, and as far as the authors are aware, there has been no prospective study. Neoadjuvant chemotherapy was able to avoid exenteration in all operated patients; however, residual viable tumor was present in 95% of enucleated specimens. Bilaterality and tumor in the optic nerve cut end after neoadjuvant chemotherapy were associated with inferior outcome. Compliance could be improved with computerized data entry and regular telephone contact.

RESUMO

BACKGROUND: During the past 3 decades, the incidence of colorectal cancer was at a low level in urban and rural populations in India, in comparison with figures observed in developed countries of North America and Europe. OBJECTIVE: The aim of this study was to describe the time trends of incidence and mortality, and the survival rates of colorectal cancer, as well, in India. DESIGN: This is an ecological study. MAIN OUTCOME MEASURES: The primary outcome measured is the incidence data extracted from selected Indian cancer registries in the volumes on cancer incidence in 5 continents. RESULTS: Low and stable incidence and mortality rates from colon and rectum cancers were observed in India in both men and women. However, this low incidence rate was associated with a low 5-year relative survival rate. CONCLUSIONS: It is likely that the prevailing environmental factors and lifestyle, including a reduced consumption of sugars, calories and fat-rich food, an increased consumption of vegetables and fruits, and an adequate physical activity with avoidance of overweight and obesity, are responsible for the low risk of colorectal cancers. In contrast, the low survival, even for localized cases, suggests severe deficiencies in early diagnosis and effective treatment in India. A strategy to control the disease in India, based on improving awareness of the risk factors for colorectal cancer while keeping the traditional lifestyle, and on investments in early diagnosis and adequate treatment should be implemented. However, an organized, population-based screening of colorectal cancer may not prove cost-effective, given the low burden of colorectal cancer.

RESUMO

Context: Chemoradiation is the standard of care in locally advanced non-small cell lung cancer (LA-NSCLC). Clinical presentation, disease course, and available treatment options are challenges to overcome. Little is known about the ideal timing and interaction of the two modalities, its relevance in day-to-day decision-making and the treatment outcome. Aims: The study evaluates the demographic profile, treatment pattern, outcome, and radiotherapy (RT) practice and patient care of LA-NSCLC at a tertiary cancer center. Setting and Design: This is a retrospective study from a tertiary cancer centre. Archives of patients of LA-NSCLC treated between June 2016 and June 2018 were included in our study. Materials and Methods: Clinical, demographic characteristics, treatment patterns, and outcomes were recorded. RT practice and patient care process including the integration of RT with other specialties, waiting time, and compliance to treatment were documented and analyzed. Statistical Analysis: Overall survival (OS) and progression-free survival (PFS) were the primary endpoints of the study. Log-rank test was used for univariate analysis for the factors on OS, and Cox's proportional hazards model was used for multivariate analysis for cofactors on OS. Results: Two hundred and thirty-two patients of lung cancer were treated during the study period. Fifty-four patients were squamous cell carcinoma, 108 were adenocarcinoma, and 12 were others. Out of 59 patients of LA-NSCLC, 34 underwent definitive chemoradiation. The median follow-up was 11 months (0.7-29), median overall treatment time was 44 days, median PFS was 8.9 months (range: 1.6-28.6), and median OS was 9.4 months (1.7-44.8). Time to start any oncological intervention was 1 month (0.1-4.3) and time to start RT was 2.1 months (0.1-5.4). Adherence to treatment was 91.2%. Age ≥65 and performance status ≥2 were significant for OS on univariate analysis and none on multivariate analysis. Conclusions: One-third of the cases of NSCLC present in LA stage and a third are suitable for definitive chemoradiation and only 20% undergo the planned treatment.

RESUMO

Introduction: Worldwide gastric cancer is the 5th most commonly diagnosed cancer and the leading cause of gastrointestinal cancer-related deaths. Alone surgery provides long-term survival improvements in 20% of the patients with local advanced gastric cancer. The results can be improved considering multimodal management including chemotherapy and radiotherapy. However, in low middle-income countries like India, multimodal management is challenging. Herein, we evaluated the experience of multimodal management of gastric cancer and the long-term outcome. Methods: Retrospective analysis of the data of 372 patients was done from a prospectively maintained computerized database from 1994 to 2021. Records were analyzed for demographic details, treatment patterns, recurrences, and long-term outcomes (DFS and OS). Statistical analysis was done with the package SPSS version 26 (IBM Corp, Chicago, Illinois, USA). Results: This study included 372 patients. The mean age of the patients was 54.07. A total of 307 patients (82.5%) were operated upfront, 45 (12%) received NACT, and 20 (5.5%) underwent the palliative procedure. A total of 53.2% underwent curative resection. R0 resection rate was achieved in 95% of patients. A total of 72.58% of patients required adjuvant treatment, and the majority of the patients underwent chemoradiotherapy. The most common site of metastasis was the liver. Median follow-up was 50.16 months. The 3-year disease-free survival and overall survival were 36.28% and 67.8%, and the 5-year disease-free survival and overall survival were 30.15% and 37.7%, respectively. Conclusion: Our study suggested that multimodal management is required in locally advanced gastric cancer to achieve good long-term outcomes. The treatment sequence can be tailored based on the available resources.

RESUMO

Background Percutaneous radiologic gastrostomy is an established mode of enteral feeding for nutritional support for patients with dysphagia from upper digestive tract malignancy. Its role as a rescue measure in patients with advanced malignancy, presenting with absolute dysphagia and failure of nasogastric tube insertion has not been well established. Purpose This study was performed to assess technical success and long-term outcomes of percutaneous radiologic gastrostomy (push type) for nutritional support for patients with absolute dysphagia as a last ditch nonsurgical rescue effort for enteral access. Materials and Methods This was a prospective observational study of 31 patients who underwent push-type percutaneous radiologic gastrostomy over a period of 2 years (March 2017-March 2019). The study was a part of a larger trial approved by the institutional ethics committee. Patients were followed till the removal of tube, death, or 1 year, whichever was earlier. Gastrostomy tube-related problems and complications were documented. Descriptive summary statistics were employed to analyze the success rate and complications. Results Thirty-one patients with mean age 56 years (26-78 years) including 18 males and 13 females with head and neck squamous cell cancer and esophageal cancer presenting with absolute dysphagia or significant dysphagia with failed nasogastric or endoscopic enteral access were included. Overall technical success was 93.5% (29/31), achieved in 26/31 patients with just fluoroscopy guidance and 3/5 patients with computed tomography guidance. One major (3.3%) and two minor (6.5%) complications were encountered. Five out of 29 gastrostomy tubes had to be exchanged, after a mean of 44 days (1-128 days) after insertion. Conclusion Percutaneous radiologic gastrostomy is a safe and effective intervention even as a rescue measure in patients with absolute dysphagia from advanced upper digestive tract malignancies.

RESUMO

We report the case of a 22-year old female presenting with an embryonal rhabdomyosarcoma of the cervix that was successfully treated by surgery followed by adjuvant radiation therapy and chemotherapy. She subsequently developed radiation cystitis after 10 years of follow-up. She was successfully treated with cystoscopic fulguration. In this report, we discuss a review of management strategies for cervical rhabdomyosarcoma and also throw some light on incidence and management of radiation cystitis after pelvic radiotherapy. We discuss the dose independence of radiation cystitis, which can be seen after as low as 4500 cGy of pelvic radiation.

RESUMO

PURPOSE: The incidence of symptomatic brain metastasis at diagnosis in non-small-cell lung cancer (NSCLC) is 5%-10%, and up to 40% develop during the disease course. There is a paucity of data supporting the role of brain imaging at diagnosis in asymptomatic cases particularly from resource-constraint settings. Here, we present our experience of mandatory baseline brain imaging with contrast-enhanced computed tomography (CECT) scans of all patients with NSCLC. MATERIALS AND METHODS: This was a prospective observation study of patients with NSCLC with mandatory baseline brain CECT and a CNS examination. All histology proven patients with NSCLC diagnosed between January 2018 and October 2019 were included irrespective of stage. RESULTS: A total of 496 patients were enrolled. The median age was 57 years (range, 23-84) with majority being males (75%) and smokers (66%). The prevalence of epidermal growth factor receptor mutations and anaplastic lymphoma kinase fusions was 33.4% and 12%, respectively. Brain imaging leads to upstaging in 7% cases. The prevalence of brain metastases was 21% (n = 104), with half being asymptomatic (51%). Factors associated with higher proportion of brain metastasis were young age (≤ 40 years), adenocarcinoma histology, poor Eastern Cooperative Oncology Group performance status (3 and 4), and high neutrophil-lymphocyte ratio (NLR) (> 2.5). After a median follow-up of 10.8 months (95% CI, 7.33 to 12.73), the median overall survival was 7.46 versus 12.76 months (hazard ratio 0.67; 95% CI, 0.46 to 0.96; P = .03) in patients with and without brain metastases, respectively. On multivariate analyses, high NLR and molecular graded prognostic assessment affected the overall survival significantly. CONCLUSION: In our study, 21% of patients had brain metastasis at diagnosis detected with a mandatory baseline brain imaging with CECT. NLR and molecular graded prognostic assessment are significant predictors of survival in patients with brain metastasis.
