Radical Oophorectomy for Advanced Ovarian Cancer: A Feasibility Study from Tertiary Care Cancer Centre in Eastern India.

Background: Radical oophorectomy was first performed by Hudson in order to remove an "intact ovarian tumour lodged in the pelvis, with the entire peritoneum remaining attached". We report 16 cases of radical oophorectomy done at our institute in the past 3 years and have analysed the perioperative morbidity as well as feasibility of performing the surgery without much of perioperative complication. Methods: Twenty-three patients with advanced ovarian cancer who underwent modified en bloc pelvic resection at our institute, between November 2018 and October 2021, were initially enrolled. Patients below 70 years, resectable disease on CT scan and no significant comorbidities were included. Exclusion criteria were extra-abdominal metastasis, secondary cancers or complete intestinal obstruction. Initially, 23 patients were enrolled out of which seven patients were excluded. Hence, a total of 16 patients with ovarian cancer extensively infiltrating into nearby pelvic organs and peritoneum were included. In Type 1 radical oophorectomy, retrograde modified radical hysterectomy alongwith in toto removal of the bilateral adnexae, pelvic cul-de-sac and affected pelvic peritoneum is done. Type 2 radical oophorectomy includes total parietal and visceral pelvic peritonectomy as well as an en bloc resection of the rectosigmoid colon below the peritoneal reflection. Results: Radical oophorectomy is feasible with acceptable complication rate. In our study, only one patient had burst abdomen that too due to the poor nutritional status of the patient. There was no surgery-related deaths, but one patient succumbed to pulmonary embolism 5 days after the operation. Conclusion: Hence, radical oophorectomy proves to be an effective, feasible and secure surgical technique in cases of advanced ovarian malignancies with extensive involvement of peritoneum, pelvis and visceras.

Planning and designing of an inpatient isolation facility for hematopoietic stem cell transplant patients.

During the last two decades the world has seen an increase in the use of Hematopoietic Stem Cell Transplant (HSCT) which has led to its worldwide expansion. Since, HSCT unit is an advanced set up, developing and maintaining a successful hematopoietic stem cell transplant program with a properly functioning unit enhances the credibility of any tertiary level medical facility especially for a country like ours which is in its early expanding phase of providing transplant services. The underlying principle for designing any HSCT facility is to maintain the highest possible level of aseptic environment for patients undergoing the transplant in order to prevent healthcare associated infections. Basic premises of designing the entire HSCT unit was to ensure restricted access to the facility and having an aseptic environment by implementing infection control parameters in design elements, which are explained subsequently in the article. The present manuscript describes the project experience of creating a positive pressure isolation facility for HSCT patients at a tertiary care hospital, India, which is a resource limited setting with an emphasis on need assessment, key elements in planning and designing along with the challenges associated with it.

The Utility of CD43 and CD200 in Differentiating Chronic Lymphocytic Leukemia from Other Mature B-Cell Neoplasms: A Cross Sectional Study.

To evaluate the utility of CD43 and CD200 in differentiating chronic lymphocytic leukemia (CLL) from other mature B-cell neoplasms. This was a cross-sectional study on patients diagnosed with B-cell neoplasms on flowcytometry. The median fluorescence intensity (MFI) of CD43, CD200 expressing neoplastic B-cells were compared between the CLL and non-CLL B-cell neoplasms followed by receiver operating characreristic curve (ROC) analysis. In addition, the sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) of CD43 and CD200 in diagnosing CLL were analysed. A total of 137 patients were included. The CLL group consisted 87 patients and non-CLL group consisted 50 patients. The Mann-Whitney U test showed significant CD43 expression (U = 997.5, Z= - 5.265, p < 0.001) and CD200 expression (U = 932.0, Z = - 5.5, p < 0.01) in CLL patients compared to non-CLL patients. The area under the curve were 0.771 and 0.786 for MFI of CD43 and CD200 in differentiating CLL from non-CLL group respectively. The optimal cut-off of MFI for CD43 and CD200 were 1323 and 1775 respectively. The sensitivity, specificity, PPV and NPV of CD43 in diagnosing CLL cases were 97.7%, 66%, 83.3% and 94.2% respectively. The sensitivity, specificity, PPV and NPV of CD200 in diagnosing CLL cases were 100%, 32%, 71.9% and 100% respectively. CD43 and CD200 are useful markers in differentiating CLL from other mature B-cell neoplasms with higher MFI expression of both markers found in CLL.

Clinico-pathological profile of patients with plasma cell neoplasms with special reference to bone marrow fibrosis and amyloid deposition.

To clarify the significance of bone marrow fibrosis and amyloid deposition in plasma cell neoplasm, a retrospective cross-sectional study for a period of 3 years was conducted. Patients who underwent bone marrow aspiration and biopsy with suspicion of plasma cell neoplasms were included in the study. The bone marrow findings were correlated with clinical profile of the patient along with biochemical parameters, cytogenetics, Fluorescent in situ hybridization (FISH) wherever available. A total of 273 bone marrow aspirates and biopsies of patients with suspected plasma cell neoplasms were analyzed. There were 181 male patients and 92 female patients (Male: Female = 1.96: 1). There were 245 cases of multiple myeloma (89.7%), 8 cases of primary amyloidosis (2.9%) and 6 monoclonal gammopathy of undetermined significance (MGUS) (2.1%), 5 cases of plasmacytoma (1.8%) and 4 cases of smouldering myeloma (1.4%), 5 cases of POEMS syndrome (1.8%). Bone marrow fibrosis was noted in 12 patients at diagnosis (4.3%). Among the parameters studied, only the mean Hemoglobin was significantly low in patients with marrow fibrosis. Amyloid deposition in various organs including bone marrow, kidney, liver etc., were noted in 17 patients overall (6.2%). In conclusion, the incidence of fibrosis (4.3%) and amyloidosis (6.2%) associated with plasma cell neoplasms were much lower in our study as compared to published studies.

Serial values of hematologic variables and deep venous thrombosis: Red cell distribution width is associated with deep venous thrombosis

Abstract Introduction As 30 to 50% of deep venous thrombosis (DVT) cases remain idiopathic, an increased focus on hematologic variables may therefore reveal novel correlates of DVT. Very few studies have investigated the association of hematological parameters with DVT and the causal relationship between them is still to be elucidated. Therefore, we aimed to investigate the association between serial values of hematologic variables and DVT. Methods Complete blood count parameters were serially measured at baseline and then at approximately 3-month intervals for 12 months in 152 adults with the first episode of DVT and 152 age- and sex-matched controls. The odds ratio (OR) with the 95% confidence interval (95%CI) was calculated as a measure of association between hematological parameters and DVT. Results The red cell distribution width (RDW) was the only hematologic variable which showed an independent and consistent association with DVT at all time points (multivariable-adjusted OR [95%CI] 3.38 [1.28 - 8.91] at baseline, 2.24 [0.85 - 5.92] at 3 months and 2.12 [0.81 - 5.55] at 12 months for RDW > 14.0%). This association was higher for provoked DVT than unprovoked DVT and for DVT plus pulmonary embolism than DVT alone. No significant correlation was found between the high RDW and classical thrombotic risk factors, except malignancy. Conclusions We demonstrated an independent and consistent association of the high RDW with the first episode of DVT in adult patients. The study was probably underpowered to evaluate the association between the high RDW and recurrent DVT. Further large studies with long follow-up are needed to confirm this association.

Current state of non-hematologic cancer-associated thrombosis at a tertiary care hospital in India

Abstract Introduction Cancer-associated thrombosis is a leading cause of morbidity and mortality in malignancy patients. Prophylactic anticoagulation is under-utilized and the cost of low-molecular-weight heparin (LMWH) and direct oral anticoagulants is a major barrier in developing countries. Material and methods A retrospective analysis was performed of all cancer-associated thrombosis patients attending the thrombosis clinic at a tertiary-level referral hospital based in North India between 2011 and 2015. Patient demographics and disease-related parameters were collected and analyzed. Results A total of 771 patients attended the thrombosis clinic during study period, of which 64 cases were malignancy-associated. Of these, 56% of the patients were female and 20% were bedridden. The median age was 48.5 years, adenocarcinoma (48%) being the most common histological subtype. Gynecological malignancies (30%) were the most common malignancies, followed by genitourinary (11%) malignancies. Most of the cases occurred during first year of diagnosis (51%), and only 14% occurred after 3 years. Most of the patients were on combined treatment. Almost 40% of the patients developed thrombosis within 30 days of surgical treatment. Lower limb thrombosis was the most commonly seen type (56%), while abdominal and pulmonary thrombosis were both seen in 5%. Patients were managed with LMWH and vitamin K antagonists (84.3%) and only 6.25% with LMWH alone. Direct oral anticoagulants were not commonly used during the study period. Discussion At the hospital studied, most of the cases occurred early in the disease course. Postoperative prophylaxis could have contributed towards reducing thrombosis in the peri-operative period. Early suspicion and prompt treatment can improve quality of life in such patients.
