The Efficacy of Paxman Scalp Cooling System in Preventing Hair Loss in Breast Cancer Patients Receiving Chemotherapy in Western India - Multi-centre Retrospective Cohort Study.

Aim: Chemotherapy-induced alopecia (CIA) is the most common side effect of systemic treatment in breast cancer patients. Scalp cooling gained worldwide acceptance in preventing or mitigating CIA in patients undergoing chemotherapy. The objective of this study was to evaluate the efficacy and safety of the Paxman scalp cooling system (PSCS) in Indian breast cancer patients. Materials and Methods: This is a multi-centre, retrospective-observational study including patients registered from 1st March, 2019 to 30th April, 2021 undergoing chemotherapy for breast cancer by using PSCS. The primary end-point was the incidence of CIA after completing cycles of chemotherapy. Results: A total of 91 female patients were enrolled in the study, with a median age of 53 years (IQR: 44-62 years). The prevention of alopecia (grade 0 and grade I) was seen in 81%, while more than 50% hair loss (grade 2) was seen in 16.48% after completion of treatment. The univariate analysis results showed that CIA was significantly higher in patients who received anthracyclines (OR: 2.69; 95% CI: 1.04-6.958; P = 0.041) and in patients with a post-infusion cooling time of >150 minutes (OR: 8.409; 95% CI: 2.295-30.787; P = 0.001). The incidence of grade 2 (>50% hair loss) alopecia was 81.3% in patients <6 weeks and was 18.8% at >6 weeks of start of chemotherapy (P < 0.0001). No adverse events were reported in 71.4% of patients, and the most common adverse event was headache (18.7%). Conclusion: PSCS is an effective and well-tolerated treatment modality for preventing CIA among breast cancer patients undergoing chemotherapy.

A Real-World Molecular Epidemiological Study of Non-Small-Cell Lung Cancer (NSCLC) Patients from Western India.

Ashish JoshiBackground The molecular characterization of advanced non-small-cell lung cancer (NSCLC) has unveiled genomic alterations such as EGFR gene mutations, KRAS gene mutations, ROS1 gene rearrangements, EML4-ALK rearrangements, and altered MET signaling. The objective of this molecular epidemiological study was to report the clinical, pathological, and molecular profile of NSCLC patients from western India. Materials and Methods This real-world study of NSCLC patients was performed at a chemotherapy day-care center in western India. The clinical, pathological, and molecular data were collected from the patient's medical records after obtaining the Ethics Committee permission for the study. The study was conducted according to the ethical principles stated in the latest version of Helsinki Declaration, and the applicable guidelines for good clinical practice. Results A total of 182 (58.7%) men and 128 (41.3%) women with a median age of 63 years (range: 22-93 years) were included in the study. Of the total 310 patients, 195 (62.9%) were nonsmokers whereas 81 (26.1%) had a past history of smoking. EGFR , EML4-ALK Fusion Gene, KRAS , ROS1 gene rearrangement, and PD-L1 were positive in 42 (22.3%), 12 (9%), 2 (28.6%), 3 (12.5%), and 3 (25%) patients, respectively. One patient had concurrent EGFR mutation along with ROS1 gene rearrangement. Conclusion Oncogenic driver mutations are present in Indian NSCLC patients. Molecular testing should be performed for all patients of advanced NSCLC to identify those that can benefit from newer generation of targeted or immunotherapies.

Erythroderma: An unusual manifestation of imatinib - A rare case report.

Imatinib is a tyrosine kinase inhibitor that selectively inhibits several protein tyrosine kinases which is central to the pathogenesis of human cancer. It forms the first-line treatment for chronic myeloid leukemia (CML) and gastrointestinal stromal tumors. Usually, the drug is well-tolerated with relatively few side effects. Adverse effects most commonly associated with imatinib include mild-to-moderate edema, nausea and vomiting, diarrhea, muscle cramps, and cutaneous reactions. Other side effects such as the elevation of hepatic transaminase and myelosuppression occur less frequently and resolve with interruption of imatinib therapy. Skin rash is one of the most common adverse effects of imatinib incidence of which range from 7% to 88.9%. Exfoliative dermatitis, i.e., erythroderma has been very rarely reported with this drug. We here report a rare case of erythroderma in a patient with CML on imatinib 400 mg/day therapy within 3 months of starting the treatment.

Hemangiopericytoma of supraglottis: A rare case report and review of literature.

In 1942, Stout and Murray first used the term hemangiopericytoma to describe a tumor which is distinguished histologically from other types of vascular neoplasm characterized by proliferation of pericytes. It is a rare neoplasm that was originally described as a vascular tumor derived from the pericytes. They account for 2%-3% of all soft tissue sarcomas in humans and they occur mainly in the musculoskeletal system. About 15%-30% of all hemangiopericytomas occur in the head and neck region. Hemangiopericytoma of supraglottis is very rare neoplasm with only nine cases reported in literature and ours is the tenth case overall and first case in pediatric age group. Herein, we are presenting an extremely rare case report of hemangiopericytoma of supraglottis in a 6-year-old male child who presented with stridor followed by which tracheostomy was done. Later, the patient was treated initially with radiotherapy followed by surgery, i.e., laryngectomy in view of residual disease postcurative radiotherapy. Hence, hemangiopericytoma is a very rare tumor overall and can present in pediatric age group and can be one most important differential diagnosis because many patients in this age group, stridor most commonly occurs due to the infectious causes such as influenza virus and diphtheria-induced croup, i.e., laryngotracheobronchitis.

Methotrexate-Induced Toxic Epidermal Necrolysis: A Rare Case Report and Review of Literature.

Acute lymphoblastic leukemia (ALL) is the most common malignancy in pediatric patients, and it is characterized by the presence of malignant lymphoblasts within the bone marrow and peripheral blood. The treatment of ALL involves induction, consolidation, reinduction, and maintenance therapy. Consolidation therapy in ALL-Berlin-Frankfurt-Münster 90 protocol involves the use of high-dose methotrexate (HDMTX, 5 g/m2) over 24 h as continuous infusion. The adverse effects due to HDMTX include renal dysfunction in 2%-12% patients, which can lead to increased systemic MTX exposure, leading to further myelosuppression, mucositis, hepatotoxicity, skin toxicity, and, in severe cases, multiorgan failure. Dermatologic toxicity due to MTX includes morbilliform drug rash, photoreactivation, photoenhancement, and skin hyperpigmentation. Stevens-Johnson syndrome and toxic epidermal necrolysis (TEN) are rare and possibly fatal reaction which can occur with MTX. Here, we describe a patient with B-cell ALL who developed TEN after administration of HDMTX.

Cutaneous Metastasis Leading to the Diagnosis of Carcinoma of the Prostate: A Rare Case Report and Review of Literature.

Prostate adenocarcinoma is a common urologic malignant neoplasm in man. Distant cutaneous metastases (CMs) of prostate carcinoma are extremely rare with a reported incidence of 0.36% and usually they occur late. Clinically, cutaneous metastasis of prostate carcinoma can mimic other skin conditions such as cellulitis, sebaceous cyst, zosteriform lesions, telangectasias, and more, resulting in a poor recognition. Few cases of true cutaneous metastatic prostate carcinoma exist in the literature. We present a case, where the first sign of carcinoma of the prostate was CM over the anterior abdominal wall. Radiological and histopathological confirmation pointed to a diagnosis of carcinoma of the prostate. The patient was treated with orchidectomy and was started on bicalutamide. After 1 month of bicalutamide therapy there was subjective decrease in the size of the metastasis. A high index of suspicion is required while evaluating the different differential diagnoses of this entity particularly in elderly patients.

Capillary leak syndrome in Daboia russelii bite-a complication associated with poor outcome.

Background: Capillary leak syndrome (CLS) has been previously observed as a complication of Daboia russelii bite but not clearly defined or studied in length. This observational case-control study evaluates the mortality along with associated clinical and laboratory features. Methods: Twenty-five patients who developed CLS were compared with 25 patients without CLS following Daboia russelii (Russell's viper) bite. Results: Development of CLS is associated with a significantly high risk of mortality; 11 (44%) patients with CLS died compared with 1 (4%) control (odds ratio 18.8 [95% confidence interval 2.2 to 161.99], p=0.002). Disease-defining manifestations included myalgia (22 [88%]), thirst (20 [80%]), parotid swelling (15 [60%]), conjunctival chemosis (19 [76%]) and hypotension (22 [88%]), which were unobserved in controls. Although several clinical and laboratory parameters were found to be predictive for development of CLS in univariate analysis, none of them had independent predictive value in multivariate analysis. Similarly, development of parotid swelling was the only factor with independent predictive value for mortality in multivariate analysis. Even though the number of vials of snake antivenom used is more in CLS, it seems unlikely to improve the mortality in CLS. Conclusions: This study proves that CLS is a well-defined complication of Russell's viper bite with high mortality but with clear predictors for the development of CLS and mortality.

Rare occurrence of hand-foot syndrome due to paclitaxel: A rare case report.

Hand-foot syndrome (HFS) is a relatively frequent adverse reaction to certain anticancer drugs. HFS is a type of dermatitis which has been most commonly described with 5-fluorouracil and capecitabine. However, HFS with paclitaxel is rare and has been reported sparingly in the literature. A 52-year-old male patient with recurrent carcinoma of the buccal mucosa was started on palliative chemotherapy regimen, injection paclitaxel (175 mg/m2) in combination with injection carboplatin. On post-chemotherapy day 13, the patient started developing pain, dysesthesia followed by bullae formation, and desquamation over palms and soles. Clinically, the patient had Grade 3 HFS characterized by symmetrical, tender skin lesions over the dorsal aspect of palms, and soles with desquamation necessitating interruption of treatment. Therefore, this case has been presented to be cognizant with this rare form of side effect with one of the most commonly used drug in oncology.

Tamoxifen Induced Pancreatitis: An Unusual Complication of Commonly used Drug.

Tamoxifen is a selective oestrogen receptor modulator used for the treatment of oestrogen/progesterone receptor positive breast cancer. It possess antagonistic or agonistic activity depending on the tissue location i.e., antagonistic action on breast but agonist action on endometrium and bones. The side effects of tamoxifen include hot flushes, gynaecologic symptoms (vaginal dryness, vaginal discharge), depression, forgetfulness, sleep alterations, weight gain, alteration of lipoprotein metabolism, thromboembolic disorder. Tamoxifen, like oestrogens, increases the plasma level of triglycerides and liver secretion of Very Low Density Lipoprotein (VLDL). Moreover, it inhibits the key enzymes of triglyceride metabolism. However, there are few cases of severe tamoxifen induced hypertriglyceridemia and pancreatitis. Hypertriglyceridemia is one of the risk factor for acute pancreatitis. Here we present a case of tamoxifen-induced hypertriglyceridemia and acute pancreatitis in a 50-year-old female without any comorbidity. She was treated with supportive antibiotics and supportive therapy. About one week after discharge, patient was started on letrozole 2.5 mg once a day. Clinicians must be aware of this rare side effect of tamoxifen, so baseline and periodic testing of triglyceride level must be done to avoid such complications.

Ifosfamide-induced Encephalopathy Precipitated by Aprepitant: A Rarely Manifested Side Effect of Drug Interaction.

Central nervous system (CNS) toxicity has been reported in approximately 10%-30% of patients receiving intravenous infusions of ifosfamide. Encephalopathy is a rare but serious CNS adverse reaction in these patients, and although usually transient and reversible, may cause persistent neurological dysfunction or death. Clinical features range from fatigue and confusion to coma and death. Ifosfamide forms backbone of various treatment regimens including curative treatment and palliative chemotherapy regimen. Precipitation of ifosfamide-induced encephalopathy (IIE) by aprepitant has been reported in the literature rarely. Ifosfamide is moderately emetogenic; hence, aprepitant is used to prevent emesis induced by ifosfamide. We here report a case where a patient of recurrent B-cell Philadelphia-negative acute lymphoblastic lymphoma was given aprepitant to prevent ifosfamide-induced emesis. After 24 h of ifosfamide infusion, the patient developed symptoms of encephalopathy, i.e., headache, vomiting, and one episode of seizure which was followed by disoriented behavior. After doing all routine investigations and neuroimaging, the diagnosis of IIE was kept on clinical grounds, and after looking for the various factors, we came across injection fosaprepitant as the precipitating factor. On the clinical grounds, the patient was treated with hydration and injection methylene blue for above complaints, and the patient recovered without any residual deficit within 48-72 h. Hence, in the presence of causative agent, i.e., ifosfamide and precipitating agent injection fosaprepitant with negative imaging and normal laboratory parameters as well as the early and good response to methylene blue, the diagnosis of IIE precipitated by aprepitant was confirmed.

Rituximab-induced interstitial lung disease in a patient with follicular lymphoma: A rare case report.

Rituximab is a chimeric monoclonal antibody that targets CD-20 antigen expressed in more than 90% of all B cell non-Hodgkin's lymphoma (NHL). We report a case of 33-year-old female without any comorbidities, newly diagnosed with stage IIIB follicular lymphoma treated with rituximab-based chemotherapy. Patient developed exertional dyspnea and dry cough after the fourth cycle of rituximab-based chemotherapy. Diagnostic high-resolution computed tomography (HRCT) of the lungs revealed bilateral patchy ground glass opacities suggestive of interstitial lung disease (ILD). It was managed successfully with supplemental oxygen and corticosteroids with discontinuation of the Rituximab. Extensive review of the literature did not reveal ample of material on rituximab-induced ILD (RTX-ILD).
