RESUMO
BACKGROUND: There are limited data on the role of chemotherapy in patients with small cell lung cancer (SCLC) and poor performance status (PS). METHODS: This was a retrospective analysis of a prospective observational study in patients with SCLC and PS 3 or 4. We recorded the initial therapy, symptom improvement, response rate, overall survival (OS), and the impact of various factors on OS. RESULTS: From June 2010 to August 2019, we enrolled 234 patients; 185 (79%) with PS 3 and 49 (21%) PS 4. Initial therapy was best supportive care (BSC) in 49 patients (21%), standard full dose chemotherapy in 31 (13%), and attenuated chemotherapy in 154 (66%). In 89% patients treated with attenuated chemotherapy, symptom-relief occurred at a median of 3 days (IQR, 1-7). Grade 3 and higher toxicities developed in 60% patients treated with initial attenuated chemotherapy, commonly hyponatremia in 39%, neutropenia in 16%, anemia in 11%, and infection in 10%. Grade 3 and higher toxicities as a result of standard chemotherapy occurred in 89% patients treated with upfront standard full dose chemotherapy compared to 69% of patients who received initial attenuated chemotherapy with subsequent treatment escalation. Overall, there were 6 (2.6%) toxic deaths. The response rate to chemotherapy was 77%. The median OS of the patients who received any chemotherapy was significantly longer at 6 months (95% CI, 4.8-7.2) compared to 1 month (95% CI, 0.4-1.6 months) in patients who were managed with BSC, p < 0.001; hazard ratio, 0.39 (95% CI, 0.27-0.56). The disease stage, lactate dehydrogenase level, and receipt of chemotherapy significantly impacted survival. CONCLUSION: Chemotherapy prolongs survival in patients with SCLC and poor PS. Administering an initial attenuated chemotherapy regimen followed by standard full-dose chemotherapy when the PS improves may lower toxicity and improve tolerance.

PURPOSE: There is a lack of published literature on systemic therapeutic options in cisplatin-ineligible patients with locally advanced head and neck squamous cell carcinoma (LAHNSCC) undergoing chemoradiation. Docetaxel was assessed as a radiosensitizer in this situation. METHODS: This was a randomized phase II/III study. Adult patients (age ≥ 18 years) with LAHNSCC planned for chemoradiation and an Eastern Cooperative Oncology Group performance status of 0-2 and who were cisplatin-ineligible were randomly assigned in 1:1 to either radiation alone or radiation with concurrent docetaxel 15 mg/m2 once weekly for a maximum of seven cycles. The primary end point was 2-year disease-free survival (DFS). RESULTS: The study recruited 356 patients between July 2017 and May 2021. The 2-year DFS was 30.3% (95% CI, 23.6 to 37.4) versus 42% (95% CI, 34.6 to 49.2) in the RT and Docetaxel-RT arms, respectively (hazard ratio, 0.673; 95% CI, 0.521 to 0.868; P value = .002). The corresponding median overall survival (OS) was 15.3 months (95% CI, 13.1 to 22.0) and 25.5 months (95% CI, 17.6 to 32.5), respectively (log-rank P value = .035). The 2-year OS was 41.7% (95% CI, 34.1 to 49.1) versus 50.8% (95% CI, 43.1 to 58.1) in the RT and Docetaxel-RT arms, respectively (hazard ratio, 0.747; 95% CI, 0.569 to 0.980; P value = .035). There was a higher incidence of grade 3 or above mucositis (22.2% v 49.7%; P < .001), odynophagia (33.5% v 52.5%; P < .001), and dysphagia (33% v 49.7%; P = .002) with the addition of docetaxel. CONCLUSION: The addition of docetaxel to radiation improved DFS and OS in cisplatin-ineligible patients with LAHNSCC.[Media: see text].

BACKGROUND: Triple negative Breast tumor (TNBC) is an aggressive tumor with sparse data worldwide. METHODS: We analyzed non-metastatic TNBC from 2013 to 2019 for demographics, practice patterns, and survival by the Kaplan Meir method. Prognostic factors for OS and DFS were evaluated using Cox Proportional Hazard model estimator for univariate and multivariable analysis after checking for collinearity among the variables. RESULTS: There were 1297 patients with median age of 38 years; 41 (33.3%) among 123 tested were BRCA-positives. Among these 593 (45.7%) had stage III disease, 1279 (98.6%) were grade III, 165 (13.0%) had peri-nodal extension (PNE), 212 (16.0%) lympho-vascular invasion (LVI), and 21 (1.6%) were metaplastic; 1256 (96.8%) received chemotherapy including 820 (63.2%) neoadjuvant with 306 (40.0%) pCR. Grade ≥3 toxicities occurred in 155 (12.4%) including two deaths and 3 s-primaries. 1234 (95.2%) underwent surgery [722 (55.7%) breast conservations] and 1034 (79.7%) received radiotherapy. At a median follow-up of 54 months, median disease-free (DFS) was 92.2 months and overall survival (OS) was not reached. 5-year estimated DFS and OS was 65.9% and 80.3%. There were 259 (20.0%) failures; predominantly distant (204, 15.7%) - lung (51%), liver (31.8%). In multivariate analysis presence of LVI (HR-2.00, p-0.003), PNE (HR-2.09 p-0.003), older age (HR-1.03, p-0.002) and stage III disease (HR-4.89, p-0.027), were associated with poor OS. CONCLUSION: Relatively large contemporary data of non-metastatic TNBC confirms aggressive biology and predominant advanced stage presentation which adversely affects outcomes. The data strongly indicate the unmet need for early detection to optimize care.

BACKGROUND: Oral mucositis related pain during CTRT in head and neck cancers is a common problem. Unfortunately, in spite of it being common, there is limited evidence for selection of systemic analgesic in this situation. Hence, this study was designed to compare the analgesic effect of a non-steroidal anti-inflammatory drug (diclofenac) versus a weak opioid (tramadol). PATIENTS AND METHODS: This was an open-label, parallel design, superiority randomised controlled study. In this study, head and neck cancer patients undergoing radical or adjuvant chemoradiation, who had grade 1 or above mucositis (in accordance with Common Terminology Criteria for Adverse Events version 4.03) and had pain related to it were randomly assigned to either diclofenac or tramadol for mucositis related pain control. The primary endpoint was analgesia after the first dose. The secondary endpoints were the rate of change in analgesic within 1 week, adverse events and quality of life. RESULTS: One hundred and twenty-eight patients were randomised, 66 in diclofenac and 62 in tramadol arm. The median area under the curve for graph of pain across time after first dose of pain medication for the diclofenac arm and the tramadol arm was 348.936 units (range: 113.64-1,969.23) and 420.87 (101.97-1,465.96), respectively, (p = 0.05619). Five patients (8.1%) in the tramadol arm and 11 patients (16.7%) in the diclofenac arm required a change in analgesic within 1 week of starting the analgesic (p = 0.184). There was no statistically significant difference in any adverse events between the two arms. However, the rate of any grade of renal dysfunction was numerically higher in the diclofenac arm (10.6% versus 4.8%, p = 0.326). CONCLUSION: In this phase 3 study, evaluating diclofenac and tramadol for chemoradiation induced mucositis pain, there was no statistical difference in analgesic activity of these two drugs.
RESUMO
BACKGROUND: There is paucity of data regarding clinical characteristics, laboratory parameters and outcomes of coronavirus disease (COVID-19) in cancer versus non-cancer patients, particularly from India. MATERIALS AND METHODS: This was an observational, single-centre, retrospective analysis of patients with laboratory-confirmed COVID-19 hospitalised in our institution between 22 May 2020 and 1 December 2020. We compared baseline clinical characteristics, laboratory parameters and outcomes of COVID-19 (overall mortality, time to discharge) between cancer and non-cancer patients. RESULTS: A total of 200 COVID-19 infection episodes were analysed of which 109 (54.5%) were patients with cancer and 91 (45.5%) were patients without cancer. The median age was 43 (interquartile range [IQR]:32-57), 51 (IQR: 33-62) and 38 (IQR: 31.5-49.3) years; of whole cohort, cancer and non-cancer patients, respectively. Comparison of outcomes showed that oxygen requirement (31.2% [95% CI: 22.6-40.7] vs. 17.6% [95% CI: 10.4-26.9]; p = 0.03), median time to discharge (11 days [IQR: 6.75-16] vs. 6 days [IQR: 3-9.75]; p < 0.001) and mortality (10.0% [95% CI: 5.2-17.3] vs. 1.1% [95% CI: 0.03-5.9]; p = 0.017) were significantly higher in patients with cancer. In univariable analysis, factors associated with higher mortality in the whole cohort included diagnosis of cancer (10.1% vs. 1.1%; p = 0.027; odds ratio [OR]: 7.04), age ≥60 (17.4% vs. 2.6%; p = 0.001; OR: 7.38), oxygen requirement (22% vs. 0.6%; p < 0.001; OR: 29.01), chest infiltrates (19.2% vs. 1.4%; p < 0.001; OR: 22.65), baseline absolute lymphocyte count <1 × 109 /L (10.8% vs. 1.9%; p = 0.023; OR:5.1), C-reactive protein >1 mg% (12.8% vs. 0%; p = 0.027; OR: 24.69), serum procalcitonin >0.05 ng/ml (22.65% vs. 0%; p = 0.004; OR: 4.49) and interleukin-6 >6 pg/ml (10.8% vs. 1.3%; p = 0.036; OR: 3.08). In multivariable logistic regression, factors significantly associated with mortality were oxygen requirement (p = 0.005; OR: 13.11) and high baseline procalcitonin level (p = 0.014; OR: 37.6). CONCLUSION: Cancer patients with COVID-19 have higher mortality and require longer hospital stay. High procalcitonin levels and oxygen requirement during admission are other factors that affect outcomes adversely.

BACKGROUND: Regimens for palliation in patients with head and neck cancer recommended by the US National Comprehensive Cancer Network (NCCN) have low applicability (less than 1-3%) in low-income and middle-income countries (LMICs) because of their cost. In a previous phase 2 study, patients with head and neck cancer who received metronomic chemotherapy had better outcomes when compared with those who received intravenous cisplatin, which is commonly used as the standard of care in LMICs. We aimed to do a phase 3 study to substantiate these findings. METHODS: We did an open-label, parallel-group, non-inferiority, randomised, phase 3 trial at the Department of Medical Oncology, Tata Memorial Center, Homi Bhabha National Institute, Mumbai, India. We enrolled adult patients (aged 18-70 years) who planned to receive palliative systemic treatment for relapsed, recurrent, or newly diagnosed squamous cell carcinoma of the head and neck, and who had an Eastern Cooperative Oncology Group performance status score of 0-1 and measurable disease, as defined by the Response Evaluation Criteria In Solid Tumors. We randomly assigned (1:1) participants to receive either oral metronomic chemotherapy, consisting of 15 mg/m2 methotrexate once per week plus 200 mg celecoxib twice per day until disease progression or until the development of intolerable side-effects, or 75 mg/m2 intravenous cisplatin once every 3 weeks for six cycles. Randomisation was done by use of a computer-generated randomisation sequence, with a block size of four, and patients were stratified by primary tumour site and previous cancer-directed treatment. The primary endpoint was median overall survival. Assuming that 6-month overall survival in the intravenous cisplatin group would be 40%, a non-inferiority margin of 13% was defined. Both intention-to-treat and per-protocol analyses were done. All patients who completed at least one cycle of the assigned treatment were included in the safety analysis. This trial is registered with the Clinical Trials Registry-India, CTRI/2015/11/006388, and is completed. FINDINGS: Between May 16, 2016, and Jan 17, 2020, 422 patients were randomly assigned: 213 to the oral metronomic chemotherapy group and 209 to the intravenous cisplatin group. All 422 patients were included in the intention-to-treat analysis, and 418 patients (211 in the oral metronomic chemotherapy group and 207 in the intravenous cisplatin group) were included in the per-protocol analysis. At a median follow-up of 15·73 months, median overall survival in the intention-to-treat analysis population was 7·5 months (IQR 4·6-12·6) in the oral metronomic chemotherapy group compared with 6·1 months (3·2-9·6) in the intravenous cisplatin group (unadjusted HR for death 0·773 [95% CI 0·615-0·97, p=0·026]). In the per-protocol analysis population, median overall survival was 7·5 months (4·7-12·8) in the oral metronomic chemotherapy group and 6·1 months (3·4-9·6) in the intravenous cisplatin group (unadjusted HR for death 0·775 [95% CI 0·616-0·974, p=0·029]). Grade 3 or higher adverse events were observed in 37 (19%) of 196 patients in the oral metronomic chemotherapy group versus 61 (30%) of 202 patients in the intravenous cisplatin group (p=0·01). INTERPRETATION: Oral metronomic chemotherapy is non-inferior to intravenous cisplatin with respect to overall survival in head and neck cancer in the palliative setting, and is associated with fewer adverse events. It therefore represents a new alternative standard of care if current NCCN-approved options for palliative therapy are not feasible. FUNDING: Tata Memorial Center Research Administration Council.

BACKGROUND: Blood supply to the thyroid is relatively high when compared to that of liver. Despite this documented metastatic deposit in thyroid remains a rarity. Synchronous nonthyroidal metastatic deposit in thyroid from a lung primary is relatively rare. Metastasis to thyroid portends to poor prognosis, and hence a metastatic deposit has to be excluded in any suspicious lesion of thyroid. MATERIALS AND METHODS: Details of a rare presentation of a malignant thyroid lesion, a secondary deposit from an asymptomatic primary papillary adenocarcinoma of lung, who had presented to this tertiary care center was retrieved and analyzed. RESULTS: Patient with an initial diagnosis of papillary carcinoma on FNA was taken up for total thyroidectomy and cervical lmphadenectomy. HPR was mucinous carcinoma of thyroid with high lymph nodal metastasis. In view of the exrathyroidal disease an adjuvant external beam radiotherapy was considered for him. Unfortunately, the radiotherapy planning CT scan revealed left sided lung lesions with pleural effusion which was proved to be papillary adenocarcinoma of lung on biopsy, with metastases to thyroid. He was treated with chemotherapy but he succumbed to his illness 9 months from the date of diagnosis. CONCLUSION: Although encountered rarely, metastatic lesions in thyroid from nonthyroidal primaries need to be excluded while evaluating thyroid lesions.

Adjuvant treatment in gastric adenocarcinoma has been a challenge for the treating specialists, and despite several trials, a clear consensus is yet to be defined. The higher propensity for lymph nodal involvement and locoregional recurrences led to the hypothesis that locoregional and systemic treatments need to be equally aggressive to achieve better outcomes in the management of gastric adenocarcinoma. Regional, ethnic, and biological differences between the Eastern and Western population are also found to reflect in the tumor behavior and its response to treatment. The MAGIC (Medical Research Council Adjuvant Gastric Infusional Chemotherapy), Intergroup 0116, ACTS-GC (Adjuvant Chemotherapy Trial of S-1 for Gastric Cancer), CLASSIC (Capecitabine and Oxaliplatin Adjuvant Study in Stomach Cancer), ARTIST (Adjuvant Chemoradiation Therapy in Stomach Cancer), and the recently published CRITICS (Chemoradiotherapy after Induction Chemotherapy in Cancer of the Stomach) trials were a few of the randomized controlled trials that tried to give a clearer perspective of this tumor, though it still remains a dilemma. A study incorporating the tumor and demographic factors along with the availability of skilled talent and resources might generate an answer.

BACKGROUND: Prolonged infusion of low dose gemcitabine (PLDG) in combination with platinum has shown promising activity in terms of improved response rate and progression free survival (PFS); especially in squamous non-small cell lung cancer (NSCLC). Hence, we conducted a phase 3 randomized non-inferiority study with the primary objective of comparing the overall survival (OS) between PLDG and standard dose of gemcitabine with platinum. METHODOLOGY: Adult subjects (ageâ¯≥â¯18â¯years), with stages IIIB-IV, NSCLC (squamous) and ECOG performance status of ≤ 2 were randomized 1:1 into either carboplatin with standard dose gemcitabine (1000â¯mg/m2 intravenous over 30â¯min, days 1 and 8) (STD-G arm) or carboplatin along with low dose gemcitabine (250â¯mg/m2 intravenous over 6â¯h, days 1 and 8) (LOW-G arm) for a maximum of 6â¯cycles. Tumor response was assessed by RECIST criteria version 1.1 every 2â¯cycles till 6th cycle and thereafter at 2 monthly intervals till progression. The primary endpoint was overall survival. 308 patients were randomized, 155 in STD-G arm and 153 in LOW-G arm, respectively. RESULTS: The median overall survival in STD-G arm was 6.8â¯months (95%CI 5.3-8.5) versus 8.4â¯months (95%CI 7-10.3) in the LOW-G arm (HR-0.890 (90%CI 0.725-1.092). The results with per protocol analysis were in line with these results. There was no statistical difference in progression free survival (HR-0.949; 90%CI 0.867-1.280) and adverse event rate between the 2 arms. CONCLUSION: This study suggests that PLDG is an alternative to the standard gemcitabine schedule in squamous NSCLC, and either of these can be selected subject to patient convenience.
RESUMO
Head and neck malignancies have always been challenging for the clinician, both with regards to locoregional control and distant metastasis. Aggressive approaches translate to an acceptable locoregional control, but distant failures pose a dilemma. Newer, sophisticated, imaging modalities have helped in early diagnosis of solitary metastasis, and in turn have opened up an array of interventional procedures, which to some extent improve the disease-free survival and quality of life, as was seen in the present case of locoregionally controlled advanced hypopharyngeal malignancy who presented with solitary distant metastasis. Still, diligent care needs to be taken not to aggravate the scenario with these interventions.

BACKGROUND: Curative intent treatments for malignancies using radiation therapy while achieving longer disease-free survivals, may also lead to solid second malignancies, a dreaded late complication. Both in-field as well as out-field second malignancies are encountered and lead to diagnostic dilemma, and delay in treatment. MATERIALS AND METHODS: Details of a case of rare, in-field, radiation induced leiomyosarcoma, a rare soft tissue sarcoma, in a treated case of high risk carcinoma of prostate, who presented to our tertiary care centre was retrieved and analysed. CONCLUSION: Increasingly sophisticated radiotherapy techniques, while providing state of the art treatment options, does increase the potential risk of radiation-induced second-malignancies. Respecting integral-dose carries priority, until further studies elucidates mechanism of tumorigenesis.

BACKGROUND: Breast cancer tissue is sensitive to hypofractionation. This is an analysis of patients treated with hypofractionated protocols since 2009, at our tertiary cancer center. METHODS: Details of breast cancer patients treated with adjuvant hypofractionated external beam radiation therapy (EBRT) from January 2009 to December 2014 were retrieved and analyzed. RESULTS: One thousand seven hundred and eighty patients received adjuvant EBRT during this period. Three hundred and eight were offered hypofractionated schedule. One hundred and eighty-eight had modified radical mastectomy (MRM) and 120 had breast conservation surgery (BCS). Dose was 40 Gy in 15 fractions to chest wall/breast, and tumor bed boost of 10 Gy in 5 fractions, where indicated, using three-dimensional conformal radiotherapy (3DCRT). Electrons were used in 159 and photons in 149. Single en face electron field was used for chest wall in MRM patients, and tangential photon beams for the whole breast. Patients on follow-up were assessed for locoregional recurrence, chest wall, breast or ipsilateral upper limb edema, brachial neuralgia, local skeletal events, pulmonary and cardiac symptoms, and cosmetic results. Two developed chest wall recurrence, one each in electron and photon arms. No skeletal, cardiac, or pulmonary adverse events were recorded. About 13.6% had arm edema, which was staged according to the International Society of Lymphology lymphedema staging, as Stage I-7.8%, Stage II-3.9%, and Stage III-1.9%. Twenty-six treated with electrons had arm edema. Increased incidence of arm edema in MRM patients could be attributed to combined surgical and radiation morbidity. Five-year overall survival was 81.9%. CONCLUSION: Hypofractionation is an accepted cost-effective standard of care in adjuvant breast radiation. Single en face electron field is well tolerated, and 3DCRT planning ensures homogeneous chest wall coverage, respecting dose constraints to organs at risk.

Inflammatory breast cancer (IBC) is a relatively rare and aggressive subtype, accounting for nearly 2.5% of all diagnosed breast cancers worldwide. It is usually characterised by an acute onset, rapid clinical progression, poor prognosis and micrometastasis at the time of presentation. Prompt recognition of clinical symptoms and identification of warning signs are vital in diagnosing and appropriately treating a patient with IBC.

BACKGROUND: Primary vaginal carcinoma is rare, accounting for 1-2 % of all gynecological malignancies. Being rare, most observations are based on retrospective and comparative analyses. This study was aimed to retrospectively analyze the prognostic factors and its relevance in the outcomes of primary vaginal cancers. MATERIALS: Medical records of all cases of primary vaginal cancers, presented to Department of Oncology, from 2004 to 2012, at a tertiary care center in southern India, were retrieved from electronic medical records, and were analyzed. RESULTS: The total number of cases was 32. Median age at presentation was 64.28 years. Squamous histology accounted for 84.4 %, with the rest being adenocarcinoma. Surgery was offered for five (15.6 %), and concurrent chemotherapy for 14 (43.8 %) patients. Three patients had only surgery. All others received radiotherapy. Twenty received external beam radiation (EBRT) and vaginal brachytherapy (VBT); seven only EBRT and two, adjuvant radiation. Five patients had residual disease; two, stage III, and three stage IV. Median follow-up was 55.83 months. Twelve patients were alive at last follow-up (37.5 %), while 14 were dead (43.8 %-8 of disease and 6 of other causes). Six patients were lost to follow-up (18.8 %). Twenty patients were disease free. Seven had recurrence, three loco-regional and four distant. Median overall survival (OS) was 86.1 months, disease-free survival (DFS) 90.17 months, and disease-specific survival (DSS) 97.13 months. When well and moderately differentiated tumors were taken together, the 5-year OS, DFS, and DSS rates were, 56.6, 64.3, and 82.3 %. For poorly differentiated tumors, median OS, DFS, and DSS were, 20.9, 14.6, and 20.9 months, with statistically significant advantage for better grade tumors, for DSS (p 0.050). Better 5-year OS, DFS, and DSS rates were observed for stage I + II group, with 54.9, 79.8, and 78.9 %, compared with advanced stage where the same were 54.8, 38.2, and 68.6 % (DFS-p 0.003, DSS-p 0.009). Grade and stage of tumor had statistically significant predictive value over the outcomes, while tumor size showed a significant trend. Patients treated with combination of EBRT and VBT fared well. CONCLUSION: Our study could conclude that grade of differentiation was a significant predictor of poor survival as was stage of disease. Combination of VBT and external beam radiotherapy provides good DFS.
RESUMO
CONTEXT: Radiotherapy techniques have improved over years but have also raised concerns over subsequent acute and late effects. One such complication, dysphagia, has led to much interest and optimization in treatment delivery. AIMS: The aim of this study was to compare radiation dose to dysphagia aspiration related structures (DARS) in intensity modulated radiation therapy (IMRT) and three-dimensional conformal radiotherapy (3DCRT), and assess its relation to post-treatment swallowing status, in patients of carcinoma of the anterior two thirds of tongue. MATERIALS AND METHODS: Treatment plans of patients treated with IMRT and 3DCRT, from November 2011 to December 2012, were retrieved. Swallowing structures were contoured. Dose volume histograms were generated. Constraint doses were considered based on the statistical derivations. Swallowing status was evaluated based on University of Washington Head- and Neck-related Quality-of-Life questions addressing swallowing. STATISTICAL ANALYSIS USED: IBM SPSS Statistics 20 Windows (SPSS Inc., Chicago, IL, USA) was used. Mann-Whitney U-test, Spearman's rho correlation coefficient, and receiver operating curves were used. RESULTS: Definitive statistical and subjective correlations were found to exist between doses of swallowing structures, especially the constrictor muscles, the base of the tongue and larynx. Probable mean dose constraints derived statistically clinically corroborates with the swallowing status of patients. IMRT had statistically significant advantage over 3DCRT, in terms of V30 (P - 0.051), V50 (P - 0.002), V60 (P - 0.002), and D80 (P - 0.023) for swallowing structures taken together. CONCLUSION: Our study is probably one of the few studies predicting possible mean dose constraints for superior constrictor, the base of the tongue and larynx. Further prospective studies are required to confirm these and to improve the swallowing quality.

Nasogastric intubation is a common procedure for enteral nutritional support in medical practice. Random spontaneous true knot formation in the tube is rarely encountered and is a cause of unanticipated trauma. This is a case of a true knot formation diagnosed with fluoroscopy and managed without untoward trauma.

Osseous metastasis from a primary breast cancer is common, and the skeletal related morbidity is high. However, solitary acral bony metastasis is rare and the diagnosis of these lesions poses a challenge to the physician. We describe a case of a patient treated with primary breast cancer who later presented with metastatic osteolytic bone lesions confined to a forefinger and toe.

Adjuvant treatment in gastric adenocarcinoma has been a challenge for the treating specialists, and despite several trials, a clear consensus is yet to be defined. The higher propensity for lymph nodal involvement and locoregional recurrences led to the hypothesis that locoregional and systemic treatments need to be equally aggressive to achieve better outcomes in the management of gastric adenocarcinoma. Regional, ethnic, and biological differences between the Eastern and Western population are also found to reflect in the tumor behavior and its response to treatment. The MAGIC (Medical Research Council Adjuvant Gastric Infusional Chemotherapy), Intergroup 0116, ACTS-GC (Adjuvant Chemotherapy Trial of S-1 for Gastric Cancer), CLASSIC (Capecitabine and Oxaliplatin Adjuvant Study in Stomach Cancer), ARTIST (Adjuvant Chemoradiation Therapy in Stomach Cancer), and the recently published CRITICS (Chemoradiotherapy after Induction Chemotherapy in Cancer of the Stomach) trials were a few of the randomized controlled trials that tried to give a clearer perspective of this tumor, though it still remains a dilemma. A study incorporating the tumor and demographic factors along with the availability of skilled talent and resources might generate an answer.
