RESUMO

Purvish M. ParikhCancer-associated anemia (CAA) remains a major unmet need that compromises overall survival (OS) and quality of life (QoL). Currently, available guidelines do not take into consideration the unique challenges in low- and middle-income countries (LMIC). Our CAA patients have to battle preexisting impaired nutritional status, depleted body iron stores, financial limitations, and difficulty in having easily accessible affordable healthcare. Hence, we fulfilled the need of guidelines for LMIC. A group of subject experts were put together, given background literature, met in a face-to-face discussion, voted using Delphi process, and finally agreed on the contents of this guideline document. As many as 50% of cancer patients will have significant anemia (hemoglobin < 10 g/dL) at initial diagnosis. It is most commonly seen with gastrointestinal malignancies, head and neck cancers, and acute leukemias. The hemoglobin falls further after initiation of cancer directed therapy, due to chemotherapy itself or heightened nutritional deficiency. Its evaluation should include tests for complete blood count, red blood cell morphology, reticulocyte count, Coombs test, and levels of vitamin B12 and folic acid. Iron status should be monitored using test to measure serum iron, total iron binding capacity, transferring saturation, and serum ferritin levels. A minimum of 50% of cancer patients with anemia require iron supplements. The preferred mode of therapy is with intravenous (IV) iron using ferric carboxymaltose (FCM). Most patients respond satisfactorily to single dose of 1000 mg. It is also safe and does not require use of a test dose. Significant anemia is found in at least half of all cancer patients in India, South Asian Association for Regional Cooperation region, and other LMIC countries. Its awareness among healthcare professionals will prevent it from remaining undiagnosed (in up to 70% of all cancer patients) and adversely affecting OS and QoL. The benefits of treating them with IV iron therapy are quick replenishment of iron stores, hemoglobin returning to normal, better QoL, and avoiding risk of infections/reactions with blood transfusions. Many publications have proven the value of single-dose FCM in such clinical situations. CAA has been proven to be an independent prognostic factor that adversely affects both QoL and OS in cancer patients. Use of FCM as single IV dose of 1000 mg is safe and effective in the majority of patients with CAA.

RESUMO

OBJECTIVE: To examine the microbiological profile, sensitivity of organisms, treatment and outcomes of in-patients suffering from febrile neutropenia in a tertiary healthcare centre. METHODS: Data was obtained from the Electronic Medical Health records in Aster Medcity, Cochin, IND. The study population included adult patients undergoing treatment for hematologic malignancies or solid tumors in the hospital between January 2021 and March 2023. Febrile neutropenia episodes were identified based on (1) absolute neutrophil count ≤1500 mm3, (2) at least a single recorded oral temperature of >38.0∘C (100.4∘F) sustained over a one-hour period. Febrile neutropenia consequences included ICU admission, length of ICU admission, and mortality. RESULTS: Total 115 cases of febrile neutropenia were identified in the time period from January 2021 to March 2023. Organisms were isolated from 43% of all the cultures taken. The most common organism isolated was Klebsiella pneumoniae (32.81%), followed by Escherichia coli (29.69%) and Pseudomonas aeruginosa (10.94%). Other organisms that were also isolated were Candida albicans (3.13%), Aeromonas hydrophilia, Acinetobacter baumannii, Burkholderia cepacia, Enterobacter cloacae, Enterococcus faecium, Staphylococcus epidermidis, Staphylococcus hemolyticus, Streptococcus spp, and one case of Ralstonia mannitolytica. Multi-drug resistance (MDR) was seen in 33% of isolates and extensive-drug resistance was seen in 19% of isolates. E. coli showed the highest prevalence of antibiotic resistance with 68% growing MDR isolates and 16% growing XDR isolates. ICU stay was required in 34% of patients with a median duration of stay of three days. A mortality rate of 16.52% was seen, with 17.11% in hematological malignancies and 15.38% in solid tumors. CONCLUSIONS: This study showed an increasing prevalence of Gram-negative bacterial infection in patients with febrile neutropenia. It also shows a high prevalence of antibiotic resistance in microbes in febrile neutropenia. Larger multi-hospital studies are required to better understand the microbiological profile of febrile neutropenia and identify the developing antimicrobial resistance trends.

RESUMO

We present the case of a 32-year-old healthy male who presented with a three-month history of insidious onset pain and swelling over the right tibia. Initial radiographs and imaging pointed to a diagnosis of subacute osteomyelitis, as there was no cortical destruction, periosteal reaction, or soft tissue involvement. The patient underwent surgery for osteomyelitis. However, the histopathology and immunohistochemistry (IHC) findings pointed to a possible B-cell lymphoma diagnosis. The patient was referred to a tertiary-level oncology centre, where a repeat biopsy and positron emission tomography (PET) scan confirmed a diagnosis of primary bone lymphoma (PBL). Treatment was initiated immediately in the form of a combination of chemotherapy and radiotherapy, and the progress was followed up with further scans at four-month intervals. The patient achieved remission nine months after the initiation of treatment.

RESUMO

Lung cancer is the foremost reason for cancer-related mortality among men and women. The ultimate goal of patient supervision post-diagnosis for advanced cases is to improve survival and quality of life with minimal treatment-associated side effects. With advancements in genomic medicine and a better understanding of cell signaling pathways, many actionable gene mutations have been identified in lung carcinoma, which drastically improve survival outcomes. Mutations in human epidermal growth factor receptor 2 (HER2) and epidermal growth factor receptor together are observed in nearly 1-3% of cases and act as an oncogenic driver. In the case of HER2-mutant lung cancers, there are limited approved agents, and the treatment represents a critical unmet medical need because of the poorer survival outcomes compared to patients with additional oncogenic drivers. The recent standard of care of treatment is chemotherapy, but reports suggest that compared with cytotoxic chemotherapy, patients receiving HER2-directed therapies have relatively longer median survival duration. Here, we report a case of HER2 exon 20-mutated metastatic lung adenocarcinoma patient who received trastuzumab emtansine in the third-line setting and achieved durable disease control.

RESUMO

AIM: This study was designed to retrospectively review our experience with the multimodality management of hepatoblastomas (HB). MATERIALS AND METHODS: Thirteen patients were treated for HB between 2000 and 2007. The clinical presentations, chemotherapy tolerance and response, surgical procedure undertaken, and complications were analysed. RESULTS: Median age of the population was 12 months (3-60 months), with a male-to-female ratio of 3.3:1. Nine patients were treated with neoadjuvant chemotherapy incorporating cisplatin and adriamycin. Primary surgery was done in four patients. Extent of hepatic resection in the operated patients varied. Mixed type was the predominant histopathological diagnosis. Adjuvant chemotherapy was well tolerated with no morbidity or mortality. Five-year event-free survival (EFS) and overall survival (OS) of all the 13 patients is 76.9%. All the nine patients who could complete multimodality treatment are alive with no evidence of disease or complications with median follow-up of 63 months (46-122 months). CONCLUSIONS: Treatment of HB with multidisciplinary approach was well tolerated. OS and EFS of patients were comparable with published studies.

RESUMO

A case of orbital rhabdomyosarcoma had a localised recurrence 13 years after being treated with chemo radiotherapy. Late recurrences are rare in orbital RMS. Only two cases have been reported to have recurred after five years of follow up. Pathological similarity of both the lesions and occurrence outside the irradiated field excluded a radiation-induced second neoplasm. Immunohistochemistry staining with p 53 was positive. Patient had good response to chemotherapy and radiotherapy. Surgical resection of residue showed complete necrosis. Retreatment with combined modality therapy resulted in complete remission and the patient is on follow up.
