RESUMO

AIMS: Global guidelines recommend that all older patients with cancer receiving chemotherapy should undergo a geriatric assessment. However, utilisation of the geriatric assessment is often constrained by its time-intensive nature, which limits its adoption in settings with limited resources and high demand. There is a lack of evidence correlating the results of the geriatric assessment with survival from the Indian subcontinent. Therefore, the aims of the present study were to assess the impact of the geriatric assessment on survival in older Indian patients with cancer and to identify the factors associated with survival in these older patients. MATERIALS AND METHODS: This was an observational study, conducted in the geriatric oncology clinic of the Tata Memorial Hospital (Mumbai, India). Patients aged 60 years and older with cancer who underwent a geriatric assessment were enrolled. We assessed the non-oncological geriatric domains of function and falls, nutrition, comorbidities, cognition, psychology, social support and medications. Patients exhibiting impairment in two or more domains were classified as frail. RESULTS: Between June 2018 and January 2022, we enrolled 897 patients. The median age was 69 (interquartile range 65-73) years. The common malignancies were lung (40.5%), oesophagus (31.9%) and genitourinary (12.1%); 54.6% had metastatic disease. Based on the results of the geriatric assessment, 767 (85.4%) patients were frail. The estimated median overall survival in fit patients was 24.3 (95% confidence interval 18.2-not reached) months, compared with 11.2 (10.1-12.8) months in frail patients (hazard ratio 0.54; 95% confidence interval 0.41-0.72, P < 0.001). This difference in overall survival remained significant after adjusting for age, sex, primary tumour and metastatic status (hazard ratio 0.56; 95% confidence interval 0.41-0.74, P < 0.001). In the patients with a performance status of 0 or 1 (n = 454), 365 (80.4%) were frail; the median overall survival in the performance status 0-1 group was 33.0 months (95% confidence interval 24.31-not reached) in the fit group versus 14.4 months (95% confidence interval 12.25-18.73) in the frail patients (hazard ratio 0.50; 95% confidence interval 0.34-0.74, P = 0.001). In the multivariate analysis, the geriatric assessment domains that were predictive of survival were function (hazard ratio 0.68; 95% confidence interval 0.52-0.88; P = 0.003), nutrition (hazard ratio 0.64; 95% confidence interval 0.48-0.85, P = 0.002) and cognition (hazard ratio 0.67; 95% confidence interval 0.49-0.91, P = 0.011). DISCUSSION: The geriatric assessment is a powerful prognostic tool for survival among older Indian patients with cancer. The geriatric assessment is prognostic even in the cohort of patients thought to be the fittest, i.e. performance status 0 and 1. Our study re-emphasises the critical importance of the geriatric assessment in all older patients planned for cancer-directed therapy.

RESUMO

BACKGROUND AND AIMS: Thrombotic events (TEs) have been extensively studied in adult cancer patients, but data in children are limited. We prospectively analyzed pediatric cancer-associated thrombosis (PCAT) in children with malignancies. METHODS: Children below 15 years of age with confirmed malignancies, treated at a large tertiary cancer center in India from July 2015 to March 2020 developing any TE were eligible. A standardized approach for detection and management was followed. Data were collected after informed consent. RESULTS: Of 6132 eligible children, 150 (2.44%) had 152 TEs, with median age 8.5 years and male:female of 1.83:1. Most TEs occurred on chemotherapy: 111 (74.0%). The most common site was central nervous system (CNS) 59 (39.3%), followed by upper-limb venous system 37 (24.7%). Hemato-lymphoid (HL) malignancies were more prone to PCAT than solid tumors (ST) (incidence 3.23% vs. 1.58%; odds ratio [OR] = 2.06, 95% confidence interval [CI] [1.36-2.88]; p < .001). Malignancies associated with PCAT were acute lymphoblastic leukemia (ALL) 2.94%, acute myeloid leukemia (AML) 6.66%, and non-Hodgkin lymphomas 5.35%. Response imaging done in 106 (70.7%) children showed complete to partial resolution in almost 90% children. Death was attributable to TE in seven (4.66%) children. Age above 10 years (OR 2.33, 95% CI [1.59-3.41]; p < .001), AML (OR 4.62, 95% CI [1.98-10.74]; p = .0062), and non-Hodgkin lymphoma (OR 4.01, 95% CI [1.15-14.04]; p = .029) were significantly associated with TEs. In ALL, age more than 10 years (OR 1.86, 95% CI [1.06-3.24]; p < .03), T-ALL (OR 3.32, 95% CI [1.69-6.54]; p = .001), and intermediate-risk group (OR 4.97, 95% CI [1.12-22.02]; p = .035) were significantly associated with thrombosis. The 2-year event-free survival (EFS) for HL malignancies with PCAT was 55.3% versus 72.1% in those without PCAT (p = .05), overall survival (OS) being 84.6% versus 80.0% (p = .32). CONCLUSION: Incidence of PCAT was 2.4%, and occurred predominantly in older children with hematolymphoid malignancies early in treatment. Most resolved completely with low molecular weight heparin (LMWH) and mortality was low. In hematolymphoid malignancies, PCAT reduce EFS, highlighting the need for prevention.

RESUMO

BACKGROUND: Improving outcomes in locally advanced esophageal/GEJ squamous cell cancer (SCC) is an unmet need. We investigated the addition of oral metronomic chemotherapy (OMC) following definitive chemoradiotherapy (CRT). MATERIALS AND METHODS: This was a randomized open-label integrated phase II/III study in patients with SCC of esophagus/GEJ following definitive CRT who had no radiologic evidence of progression, and no endoscopically detected disease. Randomization was 1:1 to OMC (celecoxib 200 mg twice daily and methotrexate 15 mg/m2 weekly) for 12 months or observation. The primary endpoint for the phase II portion was progression-free survival (PFS); secondary endpoints were overall survival (OS) and toxicity. P ≤ 0.2 for PFS was required to proceed to phase III. RESULTS: Between Jan 2016 and Dec 2019, we enrolled 151 patients for the phase II portion, 75 to OMC and 76 to observation. The tumor originated in the upper thoracic esophagus in 79% patients. Concurrent CRT consisted of median 63 Gy in a median of 35 fractions; concurrent chemotherapy was weekly paclitaxel + carboplatin in 91%. OMC was started at a median of 2.6 months (IQR 2.3-2.8) from CRT completion. Grade 3 or higher toxicities occurred in 18 patients (24%) in the OMC arm and 9 (12%) in the observation arm; P = 0.071. Median PFS was 25 months (95% CI, 17-58) in the OMC arm and was not attained [NA] (95% CI, 25-NA) in the observation arm; HR, 1.51, 95% CI, 1-2; P = 0.073. Median OS was 36 months (95% CI, 23-NA) in the OMC arm, and not attained (95% CI, NA-NA) in the observation arm; HR, 1.77; 95% CI, 1-2.9; P = 0.023. CONCLUSION: Oral metronomic methotrexate and celecoxib in patients who have not progressed radiologically and have no endoscopic evidence of disease following radical CRT for locally advanced esophageal/GEJ SCC does not improve outcomes and may lower survival.

RESUMO

BACKGROUND: Pregnancy associated breast cancer (PABC) is a rare entity and defined as breast cancer diagnosed during pregnancy or one-year post-partum. There is sparse data especially from low and middle-income countries (LMIC) and merits exploration. METHODS: The study (2013-2020) evaluated demographics, treatment patterns and outcomes of PABC. RESULTS: There were 104 patients, median age of 31 years; 43 (41%) had triple-negative disease, 31(29.8%) had hormone-receptor (HR) positive and HER2 negative, 14 (13.5%) had HER2-positive and HR negative and 16(15.4%) had triple positive disease. 101(97%) had IDC grade III tumors and 74% had delayed diagnosis. 72% presented with early stage (24, EBC) or locally advanced breast cancer (53, LABC) and received either neoadjuvant (n = 49) or adjuvant (n = 26) chemotherapy and surgery. Trastuzumab, tamoxifen, and radiotherapy were administered post-delivery. At a median follow up of 27 (IQR:19-35) months, the estimated 3-year event-free survival (EFS) for EBC and LABC was 82% (95% CI: 65.2-100) and 56% (95% CI: 42-75.6%) and for metastatic 24% (95% CI: 10.1%-58.5%) respectively. Of the 104 patients, 34 were diagnosed antepartum (AP) and 15 had termination, 2 had preterm and 16 had full-term deliveries(FTDs). Among postpartum cohort (n = 70), 2 had termination, 1 had preterm, 67 had FTDs. 83(including 17 from AP) children from both cohorts were experiencing normal milestones. CONCLUSION: Data from the first Indian PABC registry showed that the majority had delayed diagnosis and aggressive features(TNBC, higher grade). Treatment was feasible in majority and stage matched outcomes were comparable to non-PABCs.

RESUMO

BACKGROUND: Randomized controlled trials (RCT) of scalp cooling (SC) to prevent chemotherapy induced alopecia (CIA) did not evaluate its effect on hair regrowth (HR) and was conducted in a predominantly taxane (T) treated population. We conducted an RCT of SC in a setting of anthracycline (A) and taxane chemotherapy (CT) and assessed its effect on CIA and HR. METHODS: Non-metastatic breast cancer women undergoing (neo) adjuvant CT were randomized to receive SC using the Paxman scalp cooling system during every cycle of CT, or no SC. The primary end point (PEP) was successful hair preservation (HP) assessed clinically and by review of photographs after CT. HR was assessed at 6 and 12 weeks. RESULTS: 51 patients were randomized to SC (34) or control arm (17) in a 2:1 ratio. Twenty-five (49%) patients received A followed by T and the two arms were balanced with respect to this factor. HP rate was significantly higher in SC arm compared to control arm (56.3% vs 0%, P = 0.000004). HR was higher in SC arm compared to control at 6 weeks (89% vs 12%; P < 0.001) and 12 weeks (100% vs 59%, P = 0.0003). Loss of hair at PEP evaluation, which was a quality of life measure, was significantly lower in SC versus control arm (45% vs 82%, P = 0.016). There were no grade 3-4 cold related adverse effects. CONCLUSIONS: Women with breast cancer receiving A or T chemotherapy receiving SC were significantly more likely to have less than 50% hair loss after CT, superior hair regrowth and improvement in patient reported outcomes, with acceptable tolerance. It merits wider usage.

RESUMO

BACKGROUND: Regorafenib is considered a standard of care as third-line therapy in metastatic colorectal cancers (mCRCs). MATERIALS AND METHODS: The study was based on a computerized clinical data form sent to oncologists across the country for entry of anonymized patient data. The data entry form was conceived and generated by the coordinating center's (Tata Memorial Hospital) gastrointestinal medical oncologists and disseminated through personal contacts at academic conferences as well as through E-mail to various oncologists across India. RESULTS: A total of 19 physicians contributed data resulting in 80 patients receiving regorafenib who were available for the evaluation of practice patterns. The median age was 55 years (range: 24-75). Majority had received oxaliplatin-based (97.5%), irinotecan-based (87.5%), and targeted therapy (65%), previously. Patients were primarily started on reduced doses of regorafenib upfront (160 mg - 28.8%, 120 mg - 58.8%, and 80 mg - 12.5%). The median duration of treatment (treatment duration) with regorafenib was 3.1 months (range: 0.5-18), while the median progression free survival was 3.48 months (range: 2.6-4.3). Forty-five percent of patients required dose modifications due to toxicities, and the most common were (all grades) hand-foot syndrome (68.8%), fatigue (46.3%), mucositis (37.6%), and diarrhea (31.3%). CONCLUSIONS: Majority of physicians in this collaborative study from India used a lower dose of regorafenib at the outset in patients with mCRC. Despite a lower dose, there was a significant requirement for dose reduction. Duration of treatment with regorafenib as an efficacy end point in this study is similar to available data from other regions as it is the side effect profile.

RESUMO

BACKGROUND: Metronomic chemotherapy has shown promising results in selected patients of head and neck cancer in a small randomized study. This retrospective analysis was done to see whether the efficacy of metronomic chemotherapy in an unselected cohort of head and neck cancer patients is similar to that reported in the randomized study and the influence of the site and subsite of head and neck cancer on survival. MATERIALS AND METHODS: This was a retrospective analysis of head and neck cancer patients who received palliative metronomic chemotherapy between January 2013 and February 2015. The data of these patients were collected from our palliative chemotherapy database maintained in medical oncology outpatient department. The overall survival (OS) was calculated in days from the date of start of chemotherapy to the date of death. Patients who had not expired at last follow-up were censored during estimation of OS by Kaplan-Meier method. Factors affecting OS were identified by COX regression analysis. RESULTS: Over the stipulated time period, 340 patients received palliative metronomic chemotherapy. The median age of these patients was 48 years (22-90 years). The sites of tumor origin were oral cavity in 281 patients (82.6%), oropharynx in 33 patients (9.7%), larynx in seven patients (2.1%), hypopharynx in 12 patients (3.5%), and maxilla in seven patients (2.1%). Previous treatment was received by 286 patients (84.1%). The median time to failure was 3.5 months (interquartile range 2.0-6.0 months). The overall median survival was 155 days (95% confidence interval 140.2-169.8 days). Failure within 6 months of previous treatment was the most important factor influencing OS. There was a trend toward lower OS in patients with oral cancers (139 days vs. 210 days). Among the various oral cancer subsites, oral tongue primary had a lower OS. CONCLUSION: Oral metronomic chemotherapy has promising results when used in a selected cohort of patients but has dismal results in patients who failed within 6 months of previous treatment.

RESUMO

PURPOSE: The American Society of Clinical Oncology (ASCO) guideline recommends a high antiemetic prophylaxis for any dose of cisplatin. This hypothesis was tested by us in this analysis of solid tumor patients who received weekly cisplatin as a radiosensitizer in a dose range of 30-40 mg/m2. METHODS: This was a retrospective analysis of 181 solid tumor patients who received weekly cisplatin (in the dose range of 30-40 mg/m2) as a radiosensitizer between July 2015 and August 2015. The antiemetic prophylaxis schedule provided was classified as optimal (if a high antiemetic prophylaxis was provided) or suboptimal (if a nonhigh antiemetic prophylaxis was provided). The incidence of acute, delayed and breakthrough vomiting after chemotherapy was noted. SPSS version 20 was used for analysis. Fisher's exact test was used to determine the association between antiemetic schedule (suboptimal vs. optimal) and postchemotherapy emesis. RESULTS: In the present study, of 181 patients, only 25 patients (13.8%) received optimal antiemetic prophylaxis while the remaining 156 (86.2%) received suboptimal prophylaxis. In the cohort of patients with suboptimal prophylaxis, dexamethasone was omitted in all patients (100%) while NK receptor antagonist was omitted in 76 patients (48.7%). The rate of vomiting was lower in patients receiving optimal prophylaxis as compared to that in patients receiving suboptimal prophylaxis (12% vs. 39.75%; P - 0.005). CONCLUSION: Omission of dexamethasone followed by aprepitant was the main reason for suboptimal prophylaxis. High antiemetic prophylaxis in accordance with ASCO guidelines overall decreased the risk of emesis in patients receiving CTRT with weekly cisplatin in the dose range of 30-40 mg/m2.

RESUMO

BACKGROUND: Survivors of childhood cancer are at increased risk for several cardiometabolic complications. Obesity/overweight and metabolic syndrome have been widely reported in Western literature, but data from India are lacking. AIMS: To perform an objective assessment of nutritional status in a cohort of childhood cancer survivors (CCSs) and to find risk factors for extremes in nutritional status. SETTINGS AND DESIGN: The study was a retrospective chart review of CCSs who attended the late effects clinic of a referral pediatric oncology center over the period of 1 year. MATERIALS AND METHODS: An objective assessment of nutritional status was done, and results were analyzed in two groups: Adult survivors (present age <18 years) and child and adolescent survivors (CASs) (<18 years). The data were then analyzed for possible risk factors. RESULTS: Six hundred and forty-eight survivors were included in the study; of these, 471 were <18 years at follow-up, and 177 were 18 years or older. The prevalence of obesity, overweight, normal, and undernutrition was 2.6%, 10.8%, 62.7%, and 28.8% (CASs) and 0%, 8.5%, 62.7%, and 28.8% (adult survivors), respectively. Factors predictive of overweight/obesity were an initial diagnosis of acute lymphoblastic leukemia, or brain tumor and follow-up duration of >20 years or current age >30 years in adult survivors. CONCLUSIONS: The prevalence of obesity/overweight is lower in our cohort when compared to Western literature. It remains to be clarified whether this reflects the underlying undernutrition in our country, or whether our cohort of survivors is indeed distinct from their Western counterparts. Comparison with age/sex-matched normal controls and baseline parameters would yield more meaningful results.

RESUMO

BACKGROUND: Risk stratification of patients with febrile neutropenia (FN) into those at "High Risk" and "Low Risk" of developing complications helps in making decisions regarding optimal treatment, such as whether to treat with oral or intravenous antibiotics, whether to treat as inpatient or outpatient and how long to treat. Risk predictors obtained from Western studies on pediatric FN are unlikely to be relevant to low middle-income country (LMICs). Our study aimed to identify clinical and laboratory parameters predictive of poor outcomes in children with chemotherapy-induced FN in a LMIC. PROCEDURE: Two hundred and fifty consecutive episodes of chemotherapy-induced FN in pediatric (<15 years) patients were analyzed prospectively. Adverse outcomes were defined as per SPOG 2003 FN study as serious medical complications (SMC) due to infection, microbiologically defined infection, and radiologically defined pneumonia (RDP). Variables found to be significant for adverse outcome (P < 0.05) on univariate analysis were selected for multivariate analysis. RESULTS: Five factors that were found to independently predict adverse outcome were (a) previously documented infection in the past 6 months, (b) presence of significant focus of infection, (c) absolute phagocyte count <100/mm3, (d) peak temperature more than 39°C in this episode of FN, and (e) fever lasting more than 5 days during this episode of FN. CONCLUSIONS: Identifying the risk factors for adverse outcome in pediatric FN, which are objective and applicable across LMICs would contribute in developing guidelines for the management of FN in a resource-limited setting.

RESUMO

BACKGROUND: Infection or colonization with multidrug-resistant organisms (MDRO) is associated with high mortality and morbidity. Knowledge of MDRO colonization may help in planning empirical antibiotic approach in neutropenic patients, which is known to improve patient outcomes. While routine cultures are positive and may help direct antibiotic therapy in only up to 15% neutropenic patients, surveillance cultures are positive in more than 90% of cancer patients. AIMS: To assess the rate of MDRO carrier status at presentation and rate of conversion to MDRO during the treatment. MATERIALS AND METHODS: Rectal swabs of all the outpatients presenting to pediatric oncology unit were sent within 7 days from date of registration from January 2014 to December 2014. Furthermore, stool cultures/rectal swabs of all patients who got directly admitted to the pediatric ward at presentation were sent within 24 h. Repeat rectal swabs were sent again for patients from this cohort when they got readmitted to the ward at least 15 days after last discharge or when clinically indicated. RESULTS: Baseline surveillance rectal swabs were sent for 618 patients, which included 528 children with hematological malignancies and 90 children with solid tumors. Forty-five (7.3%) showed no growth. Of the remaining 573, 197 (34.4%) patients were colonized by two organisms and 30 (5.2%) by three organisms. Three hundred and thirty-four (58.4%) showed extended spectrum beta-lactamase (ESBL) Enterobacteriaceae, of which 165 (49.5%) were ESBL sensitive to beta-lactam with beta-lactamase inhibitors combinations and 169 (50.5%) were resistant to combinations. One hundred and sixteen (20.2%) were carbapenem-resistant Enterobacteriaceae (CRE) and 65 (11.4%) had vancomycin-resistant enterococci in baseline cultures. Only 63 (21%) patients were colonized by a sensitive organism in their baseline surveillance cultures. Morbidity (Intensive Care Unit stay) and mortality was higher in patients colonized by MDR organisms. There was a significant correlation between the place of residence and CRE colonization status with the highest rate (60%) of CRE colonization observed in children from East India. The repeat cultures showed the further conversion of sensitive isolates to MDRO in 80% of these children, of which 40% each converted from non-ESBL and non-CRE to ESBL and CRE, respectively. CONCLUSION: This is the first study illustrating the alarming high prevalence of community-acquired MDRO colonization, especially CRE, which has grave implications for therapy for children with cancer potentially compromising delivery of aggressive chemotherapy and affecting outcomes. This incidence further increases during the course of treatment. Knowing the baseline colonization also guides us for the planning of chemotherapy as well as antibiotic approach and infection control strategies. Local antibiotics stewardship including education of the healthcare workers as well as national level interventions to prevent antibiotic misuse in the community is critical to minimize this problem.

RESUMO

BACKGROUND: Blood stream infections (BSI) are among the most common causes of preventable deaths in children with cancer in a developing country. Knowledge of its etiology as well as antibiotic sensitivity is essential not only for planning antimicrobial policy, but also the larger infection prevention and control measures. AIMS: To describe the etiology and sensitivity of BSI in the pediatric oncology unit at a tertiary cancer center. MATERIALS AND METHODS: All the samples representative of BSI sent from pediatric oncology unit during the period of January to December, 2013 were included in the study, and analyzed for microbiological spectrum with their antibiotic sensitivity. RESULTS: A total of 4198 samples were representative of BSI. The overall cultures positivity rate was 6.97% with higher positivity rate (10.28%) from central lines. Of the positive cultures, 208 (70.9%) were Gram-negative bacilli (GNB), 71 (24.2%) were Gram-positive organisms, and 14 (4.7%) were Candida species. Lactose fermenting Enterobacteriaceae i.e., Escherichia coli (28.4%), Klebsiella pneumoniae (22.1%), and Enterobacter (4.8%) accounted for 55.3% of all GNB. Pseudomonas accounted for 53 (25.5%) and Acinetobacter 19 (9.1%) of GNB. Among Gram-positive isolates, staphylococci were the most frequent (47.8%), followed by Streptococcus pneumoniae 17 (23.9%), beta-hemolytic streptococci 11 (15.5%), and enterococci 9 (12.68%). Of GNB, 45.7% were pan-sensitive, 24% extended spectrum beta-lactamase (ESBL) producers, 27% were resistant to carbapenems, and 3.4% resistant to colistin. Pseudomonas was most sensitive, and Klebsiella was least sensitive of GNB. Of the staphylococcal isolates, 41.67% were methicillin-resistant Staphylococcus aureus (MRSA) and 10% of Coagulase Negative Stapylococci (CONS) were methicillin. CONCLUSION: A high degree of ESBL producers and carbapenem-resistant Enterobacteriaceae is concerning; with emerging resistance to colistin, raising the fear of a return to the preantibiotic era. An urgent intervention including creating awareness and establishment of robust infection control and antibiotic stewardship program is the most important need of the hour.

RESUMO

CONTEXT: Indian febrile neutropenia (FN) data are limited, especially in adult solid tumor patients. AIMS: The aim was to study patterns of presentation, source of infection, management and outcome and to evaluate the factors which may correlate with outcome. MATERIALS AND METHODS: A retrospective analysis of prospective data of FN patients at a tertiary care oncology teaching hospital in India between 2007 and 2012. A standardized form was filled for each patient. Patient management was at the discretion of the treating physician. Multinational Association for Supportive Care in Cancer (MASCC) score was retrospectively calculated. Failure of therapy was defined as death, organ failure, shifting from outpatient to inpatient or requirement of intensive care support. SPSS version 16 was used for analysis. RESULTS: A total of 388 FN episodes were included: 256 in hematolymphoid and 132 in solid tumor patients. 156 episodes were high-risk by MASCC score. Focus of infection was clinical in 45% and radiologic in 16%. Blood cultures were positive in 18% cases, most commonly Gram-negative organisms (72%). 93% patients were treated with an antibiotic combination of third-generation cephalosporin/beta-lactamase inhibitor, with aminoglycoside or fluoroquinolone. Antibiotic sensitivity to ceftriaxone was low at 38% while sensitivity to cefoperazone/sulbactam and piperacillin/tazobactam ranged between 50% and 55% and for carbapenems 75%. Failure of therapy occurred in 156 episodes, most commonly due to the need for second line antibiotics. Mortality was 5.5%. On univariate analysis, MASCC score, age, type of malignancy, prophylactic growth factors, presence of focus of infection, hemoglobin and nadir platelet count correlated with FN complications. CONCLUSION: Gram-negative bacteremia continues to be the predominant cause of FN in our setup.

RESUMO

BACKGROUND: The current standards for empirical broad-spectrum intravenous antibiotic (AB) treatment, combined with hospitalization, are cautious and safe, but lead to over-treatment of a substantial group of patients. We need to validate parameters to identify these low-risk febrile-neutropenia (FN) patients, who could then be safely treated in an outpatient setting with minimal/no AB treatment. MATERIALS AND METHODS: A retrospective analysis for validation of a risk-assessment model in FN patients was done on a patient population from January 2007 to December 2008. Inclusion criteria were a histological diagnosis of malignancy, FN secondary to chemotherapy, absolute-neutrophil-count of ≤ 500/µl, axillary temperature of ≥ 38°C, and age ≥ 14 years. Other clinical and laboratory parameters were explored for risk stratification during the FN episodes. Receiver-operating characteristic curves were used to find the threshold value, an Chi-square analysis was done to find the association between the outcome and the parameters. RESULTS: A total of 178 FN episodes were documented; 22 in solid tumors and 156 in hematolymphoid malignancies. Culture positivity was documented in 59 episodes; peripheral blood was the most common source, with Escherichia coli being the most common organism identified. Risk stratification was done using the Multinational Association of Supportive Care in Cancer (MASCC) risk-index score. The association between the MASCC score and risk stratification could not be established (P = not significant) at a score of ≤ 21; however, it was found to be significant at a score of ≤ 18. The total number of complications was 23 (sepsis 22, mortality 23). Other factors found to be significantly associated with a high risk of complications in the univariate analysis were, mucositis (P = 0.03), maximum temperature ≥ 103°F (P = 0.01), tachycardia (P < 0.001), tachypnea (P = <0.001), age (P = 0.006), high dose of steroid (P < 0.001), total duration of fever (≥ 2.5 days (for which sensitivity (S) and specificity (Sp) were 87 and 81%, respectively), serum-creatinine (≥ 0.45 mg%, S = 100%, Sp = 97%), serum-bilirubin (≥ 0.5 mg/dl, S = 100%. Sp = 90%), requirement of second-line antibiotics (P = 0.02), intensive-care (P ≤ 0.001), ventilatory support (P < 0.001), and requirement of packed cell (PC) transfusion (P = 0.02). In the multivariate analysis, mucositis (P = 0.02), HD steroid use (P = 0.026), and PC requirement (0.026) were identified as independent variables. CONCLUSIONS: The MASCC risk-index score was found to be meaningful at a score of ≤ 18. Other clinical and laboratory parameters were found to have a strong association with risk stratification in cancer patients during FN episodes.

RESUMO

BACKGROUND: Infection is a common cause of mortality and morbidity in cancer patients. Organisms are becoming resistant to antibiotics; age appears to be one of the factors responsible. We analyzed common organisms and their antibiotic sensitivity pattern in the correlation with age. METHODS: This is a single institutional, retrospective analysis of all culture positive adult and pediatric cancer patients from January 2007 to December 2007. For statistical analysis, Chi-square test for trend was used and P values were obtained. Of 1251 isolates, 262 were from children <12 years of age and 989 were from adolescents and adults (>12 years of age). Gram-negative organisms were predominant (64.95) while Gram-positive constituted 35.09% of isolates. RESULTS: The most common source in all age groups was peripheral-blood, accounting to 47.8% of all samples. The most common organisms in adults were Pseudomonas aeruginosa (15.3%) while in children it was coagulase negative Staphylococcus aureus (19.8%). Antibiotic sensitivity was different in both groups. In pediatric group higher sensitivity was seen for Cefoparazone-sulbactum, Cefipime, Amikacin, and Tobramycin. No resistance was found for Linezolid. CONCLUSIONS: The isolates in both children and adults were predominantly Gram-negative though children had proportionately higher Gram-positive organisms. High-dose cytarabine use, cotrimoxazole prophylaxis, and frequent use of central lines in children especially in hematological malignancies could explain this observation. Children harbor less antibiotic resistance than adults; Uncontrolled, cumulative exposure to antibiotics in our community with increasing age, age-related immune factors and variable bacterial flora in different wards might explain the higher antibiotic resistance in adults. Thus age is an important factor to be considered while deciding empirical antibiotic therapy.

RESUMO

INTRODUCTION: Historically, metastatic renal cell carcinoma (RCC) has had poor prognosis; the outcomes have improved with the introduction of tyrosine-kinase inhibitors, such as sunitinib. There is no reported literature from India on the use of sunitinib in metastatic RCC. We present an analysis of sunitinib at our institute over 4 years. MATERIALS AND METHODS: An unselected population of patients with metastatic or relapsed metastatic RCC receiving sunitinib was analyzed with respect to patient characteristics, response, toxicity, and outcomes. RESULTS: Fifty-nine patients (51 males, 8 females) with a median age of 55 years were included in the study. Lungs and bones were the most common site of metastases. The patients received a median number of 4 cycles, with 23 patients requiring dose-modification and 12 discontinuing therapy due to toxicity. Overall, 38 patients (65%) had CR, PR, or standard deviation while 14 had progression or death at initial evaluation. The median progression-free survival (PFS) was 11.4 months and overall survival was 22.6 months. Hand-foot syndrome, fatigue, mucositis, skin rash, and vomiting were seen more often among our patients, whereas hypertension was not as common compared with previously published reports. CONCLUSION: Sunitinib is a viable option for the treatment of metastatic RCC and shows a comparable PFS in Indian patients. Although toxicity remains a concern, most of the adverse effects can be managed conservatively. Careful patient selection, tailoring the dose of therapy, adequate counseling, and careful follow-up is essential for optimum therapy.

RESUMO

CONTEXT: Head and neck cancers in developing countries present with advanced disease, compounded by poor access to tertiary care centers. AIM: We evaluated oral metronomic scheduling of anticancer therapy (MSAT) in advanced operable oral cancers, in conjunction with standard therapy. SETTINGS AND DESIGN: This was a retrospective matched-pair analysis carried out in a tertiary referral cancer center. MATERIALS AND METHODS: Advanced operable oral cancer patients having a waiting period for surgery > 3 weeks were administered MSAT. Patients then underwent standard therapy (surgery +/- adjuvant radiation/chemoradiation) as warranted by the disease, followed by MSAT maintenance therapy. Outcomes of the MSAT group were compared with stage-matched controls with similar waiting periods. STATISTICAL ANALYSIS: Survivals were found using the Kaplan-Meier method and compared between groups using the log rank test. RESULTS: Response was seen in 75% of 32 patients. Two-year disease-free survivals (DFS) in MSAT and control groups were 86.5 and 71.6%, respectively. Two-year DFS in MSAT group who received at least three months of MSAT was 94.6% (P = 0.03). CONCLUSIONS: Oral MSAT is an economical, effective, and safe adjuvant therapy for oral cancers. It has the potential for preventing progression of the disease and improving DFS.
