Pre-phase strategy to mitigate first cycle effect in diffuse large B cell lymphoma.

CONTEXT: Treatment-related toxicities in DLBCL (diffuse large B cell lymphoma) patients are higher in the initial phase of treatment (first cycle effect). Implementation of pre-phase treatment before definitive chemotherapy had been shown to alleviate some of these side-effects in a non-randomized study conducted earlier in our institute (Lakshmaiah et. al., Eur J Haematol 100:644-8, 2018). AIMS: This study was aimed at validating the role of pre-phase treatment in newly diagnosed DLBCL patients. SETTINGS AND DESIGN: All newly diagnosed patients with DLBCL above the age of 18 years were evaluated for eligibility and prospectively enrolled. A single-arm prospective study was conducted at the Department of Medical Oncology, in our institute from July 2015 to December 2019. METHODS AND MATERIAL: Patients received vincristine and prednisolone as pre-phase treatment for 7 days after which definitive chemotherapy was instituted on day 1. They were followed up for 30 days post-first cycle chemotherapy. STATISTICAL ANALYSIS USED: Paired Student's t tests and Wilcoxon signed-ranks test were used for comparison of various clinical variables as appropriate. P value of less than 0.05 was considered significant. RESULTS: Among the 180 patients who were included in study, performance status improvement was noted in significant number of patients (p < 0.001). 38.4% achieved an ECOG (Eastern Cooperative Oncology Group) performance status of 0 post-pre-phase therapy. Febrile neutropenia was observed in 12.8% in the present cohort as compared to the historical non-pre-phase cohort (34%). CONCLUSIONS: Pre-phase therapy significantly improves the performance status and diminishes neutropenia rates in DLBCL patients.

Discordance in clinical versus pathological staging in breast cancer: Are we undermining the significance of accurate preoperative staging in the present era?

BACKGROUND: The present era of individualized treatment for breast cancer is influenced by the initial disease status including the anatomical extent, grade, and receptor status. An accurate preoperative staging is the basis of treatment planning and prognostication. Our study aims to determine the discordance between the preoperative clinical and the postoperative pathological stages of breast cancer patients. METHODOLOGY: The medical records of all non-metastatic breast cancer patients from January 2017 to December 2018 who underwent upfront surgery were reviewed. They were staged as per the eighth AJCC and the concordance between the clinical (c) and pathological T (tumor), N (nodal), and final AJCC stage was studied. A Chi-square test was used to determine factors that significantly correlate with disease discordance. RESULTS: A total of 307 breast cancer patients were analyzed. Among these, 43.3% were hormone receptor-positive, 30.6% were Her2 positive and 26% were triple-negative. Overall stage discordance was seen in 48.5% (n = 149) patients (upstaging in 22.1%, downstaging in 26.4%). The discordance rate was 48.9% for T stage (cT versus pT) and 57.4% for N stage (cN versus pN). Among patients with clinically node-negative disease, 53.4% were found to have positive nodes on histopathology, while 27.2% had vice versa. Overall, the factors associated with upstaging were ER-positive, Her2 positive and triple-negative status (all p < 0.05), while none of the factors showed significant association with downstaging. CONCLUSIONS: About half of breast cancer patients had discordance between clinical and pathological staging with higher discordance in the nodal stage. This changes the disease prognosis, and may also affect the offered surgical treatment and radiotherapy. Thus highlighting the need for a precise pre-operative staging. Also, this information will aid clinicians in discussions with patients, keeping in mind the likelihood of change in disease staging and management.

Rapidly Progressing Plasma Cell Leukemia with Underlying Plasmablastic Morphology: A Rare Case Report of a 25-Year Old Male.

Multiple myeloma constitutes a wide spectrum of diseases, ranging from slow-growing monoclonal gammopathy of undetermined significance to rapidly progressing plasma cell leukemia. It is a very rarely diagnosed hematological malignancy in those less than 30 years of age. A 25-year-old male presented with complaints of fatigue and low-grade fever. On investigation, he was found to have bicytopeina and features of tumor lysis syndrome. Initially, this was thought to be indicative of acute leukemia. However, upon further analysis with bone marrow biopsy, serum protein electrophoresis, and immunofixation, it was determined that the patient had an IgG myeloma with plasmablastic morphology. It rapidly progressed and the peripheral smear started showing clusters of plasma cells suggesting a picture of plasma cell leukemia. The patient succumbed to this aggressive disease despite treatment. This case illustrates that myeloma should also be included in the differential diagnosis for young patients, especially the rare plasmablastic variant, which can be misdiagnosed as acute leukemia. The aggressive morphology also tends to show rapid progression to plasma cell leukemia, which has a poor prognosis.

Metastatic hormone receptor-positive breast cancer in CDK 4/6 era: An outcome audit.

BACKGROUND: The treatment landscape of metastatic hormone receptor (HR) positive breast cancer has been changed in recent years. Availability of CDK 4/6 inhibitor and other hormone therapy has changed the treatment algorithm for these patient, we retrospectively analyzed our metastatic HR positive breast cancer patients. MATERIALS AND METHODS: In this study, we retrospectively analyzed the case records of hr positive metastatic breast cancer patient treated at department of medical oncology from October 2016 to September 2018. Demographical characteristics, site of metastasis, objective response and clinical benefit response and toxicity profile were analyzed. RESULTS: We treated a total of 178 patients of MBC with HT at our center during the study period. One hundred fifty-two patients received HT alone (control group) and 26 patients received HT and CDK 4/6 inhibitor (study group). The median age of patients was 56 and 58 years in the control group and study group. The ORR was 41.7 versus 57.9 (95% CI [1.01-2.56]), and the CBR was 66.1% versus 78.9%; (CI [1.18-3.56]) (P < 0.05) of the patients in control and study groups, respectively. CONCLUSIONS: Among patients with HR-positive, advanced breast cancer, hormone therapy is efficacious addition of CDK 4/6 inhibitor improve the efficacy with tolerable side effects.

A Pilot Study on the Addition of Tramadol or Eutectic Mixture of Local Anesthetics (Prilocaine Plus Lignocaine) to Local Lignocaine Infiltration for Prevention of Bone Marrow Aspiration/Biopsy Associated Pain.

Objectives Bone marrow aspiration although being a common procedure is associated with significant pain and its reduction remains an unmet need. We evaluated the use of tramadol and eutectic mixture of local anesthetics (prilocaine plus lignocaine) (EMLA) for reducing the severity of pain. Materials and Methods In this pilot study, we compared the addition of either tramadol 50 mg per oral (T) or EMLA local application (E) or no intervention (L) in addition to the usual procedure of local infiltration with lignocaine 2% before bone marrow aspiration and biopsy (BMAB) in adults suspected/confirmed with malignancy. Both, tramadol and EMLA were administered 1 hour prior to the procedure. Primary end point was reduction in pain intensity with these interventions compared with local infiltration alone. Pain was assessed using numerical FACES pain scale, a visual analogue scale. Secondary end points were to see the effect on pre procedure apprehension and to find out the other factors associated with increased pain related to the procedure. Statistical Analysis and Results A total of 300 patients were included in the study, 100 each in tramadol (T), EMLA (E), and only lignocaine local infiltration (L) arms, respectively. The mean pain intensity on the visual scale was significantly lower in the tramadol arm (T, E, L-3.4, 4.4, 4.7, respectively) ( p < 0.0005). There was a significant reduction in percentage of patients who experienced moderate/severe pain (four or more) in the tramadol arm (T, E, L-45, 77, 82%, respectively) ( p < 0.0005). Duration of procedure >10 minutes, body mass index >30, ECOG (Eastern Oncology Group) performance status ≥3, and age >50 years were positively correlated with more pain. Leukemia patients experienced significantly more pain compared with patients with lymphoma and other solid malignancies. Tramadol was well tolerated. No significant effect on pre-procedure apprehension was noted in any of the arms. Conclusion Tramadol appears to have a preventive effect on bone marrow aspiration/biopsy-associated pain and appears to be well tolerated, whereas EMLA was not associated with such an effect. Larger studies may be done to ascertain the same.

Evolution of the treatment of primary central nervous system lymphoma in a Regional Cancer Center of South India: Impact of high-dose methotrexate on treatment outcome.

OBJECTIVE: Primary central nervous system lymphoma (PCNSL) is a rare form of aggressive extranodal non-Hodgkin lymphoma. This study attempts to delineate the clinicopathological and radiological profile of PCNSL cases at our center. MATERIALS AND METHODS: All the pathologically confirmed PCNSL cases between January 2007 and July 2016 were analyzed retrospectively. The influence of potential prognostic parameters and therapeutic strategies on survival was investigated by log-rank test and Cox regression analysis. RESULTS: Of the 53 PCNSL patients, 34 (64%) patients were males. Median age at diagnosis was 44 years (range 22-65 years). The most common location in the brain was the cerebral hemispheres in 32 patients (60%), and 16 patients (30%) had multiple intracranial lesions. Histologically, all patients were diffuse large B-cell lymphomas, except one case of anaplastic large-cell lymphoma. The median survival of the patients received whole-brain radiation alone ( n = 6), standard CHOP chemotherapy + radiation ( n = 14), and DeAngelis protocol ( n = 31) was 8 months, 13 months, and 23 months, respectively. Among the 31 patients treated with DeAngelis protocol, Memorial Sloan Kettering Cancer Center Class 1 ( n = 23) and Class 2 ( n = 8) patients had a median overall survival (OS) of 25 months and 13 months, respectively. The incidence of treatment-related neurotoxicity was significantly higher with DeAngelis protocol, in comparison to CHOP + whole-brain radiation therapy (26% vs. 14%, P < 0.05). CONCLUSION: None of the potential prognostic factors had a statistically significant influence on OS in our patients. High-dose methotrexate-based chemotherapy combined with radiation was the only factor, which had a significant impact on survival (log-rank P = 0.000) but at the cost of increased neurotoxicity.

Primary mucinous carcinomas of the lung: Clinical characteristics and treatment outcomes.

INTRODUCTION: Invasive mucinous adenocarcinoma (IMA) of the lung is a distinct histologic variant of adenocarcinomas comprising about 2%-10% of lung adenocarcinomas. A large proportion of IMAs carry KRAS mutations and only rarely epidermal growth factor receptor (EGFR) mutations or ALK/ROS translocations; thus, most cases are not amenable for targeted therapy at present. This study was conducted to elicit the unique clinicopathological characteristics of IMA. MATERIALS AND METHODS: Medical records of patients diagnosed with IMA by needle biopsy at Kidwai Cancer Institute, Bangalore, from 2013 to 2018, were retrieved and reviewed. Statistical analysis was performed using SPSS version 23.0 (IBM Corp., Armonk, NY, USA). RESULTS: Four hundred and ninety cases of needle biopsy of the lung were diagonosed at our institute between January 2013 and December 2018. Nine cases (1.8%) were diagnosed as IMA. The median age of presentation was 59 years. Six (66.7%) were current smokers with pack-year > 20. Three (33.3%) of the cases were initially misdiagnosed as pneumonia in view of computed tomography findings. The lung was the most common site of metastasis (77.8%). Serum Carcinoembryonic Antigen (CEA) was elevated in six cases (66.7%). None of the cases had any driver mutations in EGFR gene or ALK and ROS1 translocations. All cases were treated with pemetrexed-carboplatin doublet followed by pemetrexed maintenance till progression. The median progression-free survival (PFS) was 15 months (range: 5-18 months). Docetaxel was given as the second-line chemotherapy in all progressed patients. Best response noted was stable disease, seen in 4 (57.1%) cases. The median PFS for docetaxel was 6 months (range: 3-8 months). The median overall survival was 22 months (range: 9-27 months). Patients with initially raised CEA at progression had a serial rise in serum CEA. CONCLUSIONS: IMA is rarely diagnosed on needle biopsies due to insufficient tissue. They mimic pneumonia on imaging, thus delaying diagnosis. EGFR mutations, ALK, and ROS1 translocations are usually negative making them ineligible for tyrosine kinase inhibitors. Response to chemotherapy is modest.

CML in Elderly: Does Age Matter?

The median age of diagnosis for chronic myeloid leukemia (CML) in India is 35 years on the contrary to western literature which is 47 years. The outcome of the elderly patient in CML TKI era is not reported from the Indian population. However, Western literature suggests that use of TKI alleviate the adverse impact of age in outcomes of CML. This study was carried out to analyze the clinical profile and outcome of elderly, in comparison with younger patients with CML. We retrospectively analyzed CML patients treated at our department from January 2008 to December 2017. The data cutoff date was December 2018. The cohorts of 712 patients were divided into two groups. Patients belonging to the age group of ≥ 60 years were classified as the study group and those who were 18-60 years were used as controls. Patient's clinical history, examination and milestones in terms of achieving hematological, molecular responses and toxicity profile were also recorded. The total of 712 patients, 52 patients in the study group and 660 patients in the control group were treated during the study period. The study group was having more co-morbidities than the control group (15.3% vs. 4.5%). Patients having high-risk EUTOS score were similar in both groups (38.4% vs. 37.6%). The patients presented in blast phase were higher in the study group as compared to control group (9.6% vs. 6.36%) but the differences were not statistically significant. Rates of achieving a hematological response at 3 months (85.1% vs. 86.89%) and the major molecular response at 18 months (54.3% vs. 60.16%) were almost similar in both groups. However, hematological toxicity, muscle cramps and gastritis were reported more in elderly patients. The outcome of CML patients in TKI era do not differ in elderly patients. However, toxicity profile was not significantly inferior in elderly patients.

Socioeconomic and administrative factors associated with treatment delay of esophageal and gastric carcinoma: Prospective study from a tertiary care centre in a developing country.

This study was aimed to analyze the spectrum of time intervals, from the onset of symptoms to the commencement of treatment in esophagogastric cancers. Factors influencing these time delays and correlation between these time points with variables including socioeconomic strata, educational level, histopathology, location of tumor and the initial modality of treatment were assessed. STUDY SETTING AND METHODS: A prospective analysis of patients with esophagogastric cancer presenting to a single tertiary care unit over a period of 12 months was performed. Histopathology other than adenocarcinoma and squamous cell were excluded. RESULTS: 202 patients were enrolled in the study. Most patients presented with advanced disease, i.e. 91.5 % of esophageal and 90 % of gastric malignancies belonged to either stage 3 or stage 4 as per American Joint Committee on Cancer (AJCC) tumor-node-metastasis (TNM) staging system. The median delay from the appearance of the first symptoms to initiation of treatment was 15 weeks (range 4-64). Patient related factors contributed to a significant delay [median of 5 weeks (range 1-24)]. Administrative factors were responsible for median delay of 3 weeks (range 0.5-20). Curative multimodality treatment was administered in 62.5 % of patients. Significant longer delay was influenced by socioeconomic strata, educational level, evaluation by non-specialist (p < 0.05). No relationship was noted between histopathology, location of tumor or initial modality of treatment. CONCLUSIONS: Delays in our setting is much more than that is seen in Western and even some Asian countries. An important component of delay is administrative related factors. These may be intervened at the hospital level compared to other factors which may need long term community oriented approaches.

Follicular lymphoma transforming to DLBCL and reverting back to follicular lymphoma at relapse-a case report.

BACKGROUND: Transformation of low-grade follicular lymphoma to high-grade diffuse large B cell lymphoma (DLBCL) is known. However, the opposite is not commonly reported. In this report, we present a case of follicular lymphoma that underwent transformation to DLBCL. Three years after treatment for histologic transformation, the patient presented again with low-grade follicular lymphoma at the same site which is unusual in the natural history of follicular lymphoma. CASE PRESENTATION: A 50-year-old female patient presented to us with complaints of slowly progressing swelling in the neck on the left side for a duration of 1 year. Past history of the patient revealed a diagnosis of follicular lymphoma in 2004 for which the patient had taken prednisolone and chlorambucil. Details of staging were not available with the patient. After a complete work-up, she was diagnosed as DLBCL, stage IIIE. She was treated with 6 cycles of CHOP regimen. She had very good response to chemotherapy. However, she defaulted and was lost to follow-up. She presented again after 3 years with history of painless progressive swelling in the right side of the neck for the last 1 year. Examination revealed cervical lymph nodes and ascites. This time, a repeat biopsy and immunohistochemistry was suggestive of follicular lymphoma. In view of significant ascites, she was started on chemotherapy with CVP regimen. After 6 cycles, she has good partial response and resolution of ascites. She is currently on follow-up. CONCLUSIONS: We have presented a case of FL that has transformed to DLBCL after 10 years of diagnosis. After HT, she was treated with CHOP chemotherapy and the patient relapsed again after 3 years with follicular lymphoma histology. This case highlights the unique and varied natural history of follicular lymphoma that may be attributed to different subclones of malignant cells that may have arisen from a common progenitor FL cell and differential effect of chemotherapy on these subclones.

Modified Epirubicin, cisplatin, and 5-FU regimen as first-line chemotherapy in metastatic gastric or gastroesophageal junction adenocarcinoma: A Phase II study.

BACKGROUND: Epirubicin, cisplatin, and 5-FU (ECF) is one of the most commonly used first-line chemotherapy regimens in metastatic gastric cancer. However, due to protracted infusion schedule, need for special infusion pumps, and catheter-related complications, the practical utility and acceptability of standard ECF regimen are limited, particularly in resource-constrained settings including India. MATERIALS AND METHODS: In the present study, we have used a more convenient modification of the standard ECF protocol (using 5 days intravenous infusion of 5-FU at a dose of 750 mg/m2/day, given over 6 h through a peripheral venous line), in Indian patients with metastatic gastric or gastroesophageal junction (GEJ) adenocarcinoma. The primary endpoint was overall survival (OS). The secondary endpoints were overall response rate (ORR), progression-free survival (PFS), and toxicity profile. RESULTS: Between January 2014 and December 2017, 107 patients were assigned and treated with this modified ECF regimen. The median age was 52 years (range, 34-62); 66.3% were males and 36.5% of the patients had ≥ 3 metastatic disease site involvement at baseline. Dose reductions due to toxicity were required in 14.9% of the patients. The ORR was 32.7%; median PFS and OS were 5.9 months (95% confidence interval [CI]: 4.7-6.9) and 10.4 months (95% CI: 8.4-11.8), respectively. Both the hematological and nonhematological toxicities were manageable, and there was no toxicity-related death. The most frequent Grade 3-4 adverse events were neutropenia (18.7%), febrile neutropenia (13.1%), mucositis (5.6%), and diarrhea (5.6%). CONCLUSIONS: In the present study, the modified ECF regimen demonstrated significant efficacy with an acceptable toxicity profile in Indian patients with metastatic gastric and GEJ adenocarcinoma. The survival outcomes of this modified schedule were comparable with those of the standard ECF regimen, as reported earlier. Clearly, this modified and more convenient ECF protocol should be explored and validated through large prospective randomized trials.

HIV/AIDS-related lymphoma: perspective from a regional cancer center in India.

BACKGROUND: India has the third largest population of people living with HIV/AIDS (PLHA). Lymphoma is the second most common malignancy among PLHA. However, data are lacking regarding HIV/AIDS-related lymphoma (ARL) in India. This study evaluated the epidemiology and clinical outcomes of ARL from a regional cancer center in India. METHODS: This retrospective analysis included cases of ARL between March 2011 and September 2017. Data were obtained from patient record files for the assessment of epidemiology and clinical outcomes. Statistical analysis was performed using GraphPad Prism 6. Comparisons of subtype-specific survivals were performed using log-rank tests. RESULTS: Of 1,226 lymphoma cases, 80 (6.5%) were ARL. Details were available for 70 patients. The median age at diagnosis was 40.5 (9-74) years with a male:female ratio of 2:1. AIDS-defining lymphomas (ADL) constituted 78.6% of cases, while 21.4% had non-AIDS defining lymphoma (NADL). The mean CD4 counts were 193.15±92.85 and 301.93±107.95 cells/µL, respectively (t-test; P=0.0002). Extranodal involvement was present in 55.7%, B symptoms were reported in 60%, and lactate dehydrogenase (LDH) was elevated in 64.3% of patients. The median overall survival times were 6 months for plasmablastic lymphoma (PBL), 23 months for diffuse large B-cell lymphoma (DLBCL), and was not reached for Hodgkin's lymphoma (log-rank test; P=0.0011). Other histological subtype cases were too few to draw meaningful survival outcomes. CONCLUSION: ARL is a heterogeneous disease. Histologic subtype is a major determinant of the clinical outcome. ADL has significantly lower CD4 counts than those of NADL. There is an urgent and unmet need for uniform management guidelines for improving outcomes in this under-represented patient population.

T-Cell Prolymphocytic Leukemia: An Experience from a Tertiary Cancer Centre in South India.

Background: T-cell prolymphocytic leukemia (T-PLL) is a rare lymphoid malignancy with dismal prognosis. Most patients have increased lymphocyte count (>1,00,000/dL) and widespread disease at presentation. Despite high response rate seen with alemtuzumab, the disease relapse is inevitable. Materials andMethods: This was a retrospective observational study done at a tertiary cancer center in South India. All patients diagnosed with T-PLL from August 2010 to July 2015 were studied for the clinical characteristics, pathological findings and treatment outcomes. Results: Seven patients were diagnosed as T-PLL over a period of 5 years. The median age at diagnosis was 51 years. In the present series, 6 patients (86%) had splenomegaly and 3 had hepatomegaly (43%). Generalized lymphadenopathy was seen in 4 (57%) patients at presentation. Skin lesions were seen in 5 (71%) patients, whereas pleural effusion was seen in only one patient (14%). All had elevated total leukocyte count, with more than 1, 00,000/dL in 4 patients. The median survival was 5 months with different chemotherapy (CT) regimens (5 patients treated with CT and 2 received best supportive care). Conclusion: T-PLL is a rare disease with no definite treatment guidelines. At present, the best outcomes are achieved if treatment with alemtuzumab is followed by stem cell transplant, but the disease invariably relapses. Countries where affordability remains a big challenge, the best approach needs to be defined beyond the monoclonal antibodies and transplant.

Comparison of health-related quality of life with epirubicin, cisplatin plus 5-fluorouracil and docetaxel, cisplatin plus 5-fluorouracil chemotherapy regimens as first-line systemic therapy in locally advanced inoperable or metastatic gastric or gastro-esophageal junction adenocarcinoma: A prospective study from South India.

BACKGROUND: Health-related quality of life (HRQOL) is an important oncologic end point for upper gastrointestinal malignancies. Unfortunately, till date, there is no published prospective data from India, comparing the HRQOL parameters between first-line chemotherapy regimens in advanced/metastatic gastric cancer. MATERIALS AND METHODS: The present study aimed to compare the HRQOL of first-line systemic chemotherapy with epirubicin, cisplatin plus 5-FU (ECF) and docetaxel, cisplatin plus 5-FU (DCF) regimens in patients with locally advanced inoperable or metastatic gastric or gastro-esophageal junction adenocarcinoma. The secondary end points were overall response rate, progression-free survival (PFS), overall survival (OS), and toxicity profile. RESULTS: Between December 2014 and December 2016, 65 patients were treated with ECF (n = 34) or DCF (n = 31) regimen. The baseline HRQOL scores were comparable between the two study groups, with the exception of significantly poor pain and sleep difficulties symptom score in the DCF group. After three cycles of treatment, both the groups showed improvements in most of the quality of life (QOL) parameters including global QOL score, compared with their baseline status. After six cycles of chemotherapy, the ECF group showed nonsignificant deterioration for most of the QOL parameters; but on the contrary, the DCF group maintained improved scores for most of the QOL parameters. The median survival until a definitive deterioration of global QOL score was significantly better in the DCF arm in comparison to the ECF arm (7.1 vs. 5.6 months, respectively, P = 0.000). The median OS was 9.2 months with ECF and 12.5 months with DCF regimen (P = 0.000), while median PFS was 5.7 and 7.4 months with ECF and DCF regimens, respectively (P = 0.002). CONCLUSIONS: This prospective study highlighted a better impact of DCF chemotherapy on the HRQOL of patients with advanced/metastatic gastric cancer and showed the importance of QOL assessments in clinical trials to complement the risk-benefit judgment.

Induction chemotherapy in locoregionally advanced nasopharyngeal carcinoma in adults: Results from a nonendemic region.

BACKGROUND: Recently published prospective clinical trials and two meta-analyses have shown that addition of induction chemotherapy (IC) to concurrent chemoradiation (CRT) could potentially improve outcomes in comparison to CRT alone, in locoregionally advanced nasopharyngeal carcinoma (LANPC). Although it remains unclear which is the best IC regimen to be offered and for how many cycles. Unfortunately, till date, there are no published data from India regarding the outcomes of various commonly used IC regimens before CRT, in LANPC. MATERIALS AND METHODS: Patients diagnosed with LANPC from January 2012 to December 2017, who received three cycles of IC before definitive CRT were reviewed retrospectively. Patients' profile, toxicity of IC, response rates, failure-free survival, and overall survival (OS) were evaluated. RESULTS: A total 34 patients with LANPC who received IC were reviewed. The median age at diagnosis was 36 years, and the majority were males (67.6%, n = 23). Nineteen patients received IC with paclitaxel plus cisplatin regimen (TP) and the remaining 15 patients received IC with docetaxel/paclitaxel plus cisplatin plus 5-FU regimen (TPF). The overall response rates after three cycles of TP and TPF IC were 68.4% and 80%, respectively, and the corresponding rates were 84.2%and 93.3%, respectively, 2 months after completion of CRT. At a median follow-up of 24 months, 2-year failure-free survival and OS for TP arm were 78.9% and 89.5%, and the corresponding rates for TPF arm were 86.7% and 93.3%, respectively. All Grade III-IV toxicities were numerically higher with triplet IC regimen in comparison to doublet regimen. CONCLUSION: In this retrospective analysis, there was no significant difference between taxane-based doublet and triplet IC regimens, in terms of survival outcomes, although Grade III-IV toxicities were numerically higher with triplet IC regimen. Clearly, these hypothesis-generating findings should be tested in a prospective randomized setting.

Metastatic thymic epithelial tumors: A regional cancer center experience.

BACKGROUND: Thymic epithelial tumors (TET) are the most common tumors of the anterior mediastinum. Patients with advanced/metastatic disease are usually treated with palliative chemotherapy (CT). Unfortunately, even though various palliative CT regimens have been used for long time, there is a real scarcity of published Indian data regarding the experience of palliative CT in metastatic TET (mTET). MATERIALS AND METHODS: This is a retrospective analysis of mTET patients treated between January 2010 and September 2017. Patients who received at least three cycles of first-line palliative CT were included for analysis of response rates, toxicity, and survival and prognostic factors. RESULTS: Of the 49 mTET patients, 27 (55.1%) were males. The median age at diagnosis was 52 years (range: 25-65). Eighteen patients (36.7%) had Masaoka Stage IVa disease, and the rest of the patients had IVb disease. The most common site of metastasis was pleuropericardium (n = 18), followed by lungs (n = 16) and lymph nodes (n = 9). The median progression-free survival and overall survival (OS) were 11.2 months (95% confidence interval [CI], 8.7-13.6) and 20.2 months (95% CI, 17.1-22.8), respectively, for the whole cohort (n = 49). The median OS of patients with Stage IVa disease was significantly better than that of the patients with Stage IVb disease (log-rank P = 0.000). Moreover, the "responders" to first-line CT had a significantly better median OS than the "nonresponders" (log-rank P = 0.000). Various first-line palliative CT regimens were well tolerated in our patients. CONCLUSION: Adriamycin Cisplatin Vincristine Cyclophosphamide (ADOC), Cyclophosphamide Adriamycin Cisplatin, and paclitaxel + carboplatin all are viable first-line palliative CT options for mTET and showed a comparable survival in Indian patients. The present study suggested that "responders" to first-line CT and those with Stage IVa disease might have a better survival than "nonresponders" and those with Stage IVb disease, respectively.

Clinical profile and treatment outcomes of metastatic neuroendocrine carcinoma: A single institution experience.

BACKGROUND: Neuroendocrine carcinoma (NEC) is a rare tumor arising from the diffuse neuroendocrine system. Most of these present in the advanced stage and palliative chemotherapy remains the only option. The prognosis remains poor with the standard chemotherapy regimen of platinum and etoposide (EP) providing modest survival benefit. METHODS: The study was done for 3 years at a tertiary cancer center in South India. Patients with a diagnosis of metastatic NEC were analyzed for clinical and pathological characteristics. The treatment outcomes and prognostic factors were evaluated using appropriate statistical test. RESULTS: A total of 114 patients of metastatic NEC satisfied the inclusion criteria and were analyzed. Gastrointestinal including hepatobiliary tract (33%) was the most common site of primary disease followed by lung (26%), genitourinary (15%), head and neck (14%), and unknown primary (9%). On analysis of pattern of metastasis, liver (65%) was the most common site followed by bone (54%) and lung (42%). The median overall survival was 11 months with a statistically significant difference between pulmonary and extrapulmonary disease (8 vs. 13 months; P = 0.003). Ki67% value was strongly associated with prognosis (hazard ratio 0.517, 95% confidence interval; 0.318-0.840, P = 0.008) whereas age, sex, and lactate dehydrogenase level did not show any relation with survival. CONCLUSION: The outcome of advanced NEC with standard chemotherapy remains poor. Larger studies with other therapeutic and novel agents are warranted to improve the treatment outcomes.

Primary breast angiosarcoma - a single institution experience from a tertiary cancer center in South India.

INTRODUCTION: Primary angiosarcoma of the breast is a rare entity with incidence of less than 0.05% of all malignant breast neoplasms. It occurs in young females without any associated risk factors. The tumor behaves aggressively and has a poor prognosis compared to invasive ductal carcinoma. METHOD: It was a retrospective observational study done at a tertiary cancer center from January 2012 to December 2016. The medical records of patients diagnosed with primary breast angiosarcoma were reviewed for the study. Clinicopathological profile, treatment, and the outcomes were analyzed. RESULTS: Four patients were diagnosed with primary breast angiosarcoma out of 2560 breast cancer patients seen over a period of 5 years. Two had metastatic disease at presentation. Among four patients, two underwent surgery of the primary tumor, whereas, all received chemotherapy either as adjuvant or palliative setting. One patient received adjuvant radiation therapy. Three patients received 2nd line and one received 3rd line chemotherapy on disease progression. After a median follow-up of 18 months one patient was surviving on 3rd line chemotherapy with trabectedin. Other three succumbed to disease after progression. CONCLUSION: Due to a small number of this malignancy randomized studies are difficult to perform and optimum treatment strategy still need to be defined.

Primary central nervous system lymphoma in immunocompetent patients: A regional cancer center experience.

BACKGROUND: Primary central nervous system lymphoma (PCNSL) is a rare form of aggressive extranodal non-Hodgkin's lymphoma which occurs in both immunocompromised and immunocompetent patients. It has an overall poor prognosis in spite of a multimodality treatment approach including chemotherapy and radiotherapy. This study attempts to further delineate the clinicopathological, immunohistochemical, and radiological profile of PCNSL at Kidwai Memorial Institute of Oncology, Karnataka, India. MATERIALS AND METHODS: All the pathologically confirmed PCNSL cases between January 2010 and June 2016, at our center, were analyzed retrospectively. The influence of potential prognostic parameters on overall survival (OS) was investigated by log-rank test and Cox regression analysis. RESULTS: Of the 26 PCNSL patients, 17 (65.3%) were males. Median age at diagnosis was 42.5 years. None of the patients had HIV or Epstein-Barr virus positivity and only four patients (15.4%) had B-symptoms. The most common location in the brain was cerebral hemispheres in 15 patients (57%) and 10 patients (38.5%) had multiple intracranial lesions. Histologically, all were diffuse large B-cell lymphomas, except one case of anaplastic large cell lymphoma. Immunohistochemically, 18 patients (69%) had MUM 1 positivity and 20 cases (77%) belonged to nongerminal center subtype. DeAngelis protocol was followed in 24 patients (92%), and among this cohort, Memorial Sloan Kettering Cancer Center Class 1 (n = 17) and Class 2 (n = 7) patients had a median OS of 25 months and 11 months, respectively. CONCLUSION: None of the potential prognostic factors had a statistically significant influence on OS in our patients. High-dose methotrexate combined with radiation is an effective therapeutic approach. However, further prospective studies with a large number of patients are needed to identify more effective primary chemotherapy regimens to further improve the treatment outcome.

Metastatic gastrointestinal stromal tumor: A regional cancer center experience of 44 cases.

BACKGROUND: Gastrointestinal stromal tumors (GISTs) are the most common mesenchymal neoplasms of the gastrointestinal tract. Historically, a poor prognosis for metastatic disease has been reported with systemic chemotherapy. Significant advances have been made in the last decade, since the introduction of different tyrosine kinase inhibitors (TKIs). Unfortunately, even though the TKIs have been used for a long time, there are very few published data of the experience of TKI therapy in metastatic GIST from India. MATERIALS AND METHODS: Patients diagnosed with metastatic GIST from January 2005 to October 2016 at our center, who received first-line therapy with imatinib 400 mg/day, were reviewed retrospectively. Patients' profile, response to treatment, toxicity of TKI therapy, time to progression, and survival were evaluated. RESULTS: Of the 44 metastatic GIST patients, 23 (52.2%) were males. Median age at diagnosis was 48 years. The most common presenting symptom was an abdominal pain (52%), followed by weight loss (23%). Most frequently affected metastatic site was liver (57%), followed by peritoneum (16%), and lungs (4.5%). Metastases to both liver and peritoneum were found in 10 patients (22.5%). All patients were initially treated with imatinib at a dose of 400 mg/day. Disease stabilization was documented in 21 cases (48%), and 13 patients (29%) achieved a partial response. TKI therapy was well-tolerated in most cases. Median progression-free survival (PFS) was 26 months, and estimated median survival was 48 months. Patients with lung metastases have a significantly inferior median PFS and overall survival, in comparison to patients with other metastatic sites (P < 0.05). CONCLUSIONS: Imatinib therapy was well tolerated and induced a sustained clinical benefit in more than half of the patients with metastatic GIST. Lung metastases seemed to be a poor prognostic factor in this patient population.
