Medical Oncology Workload in Europe: One Continent, Several Worlds.

AIMS: The workload pressure on medical oncologists will increase in the near future. There are no comprehensive data available about the current workload of medical oncologists in Europe. Here we report the European results of a global survey of the workload of medical oncologists. MATERIALS AND METHODS: An online survey was distributed through a snowball method via national oncology societies to chemotherapy-prescribing physicians in 21 European countries. We compared the workload of medical oncologists in Eastern European countries (EECs) and Western European countries (WECs). The primary measure of workload was the annual number of new cancer patient consults seen per oncologist. RESULTS: In total, 495 oncologists from 16 European countries completed our survey: 100 from seven EECs and 395 from nine WECs. The median number of annual consults per medical oncologist was 225 in EECs compared with 175 in WECs (P < 0.001). The proportion of medical oncologists seeing more than 300 consults/year was 35% (35/100) in EECs compared with 18% (68/395) in WECs. The median number of patients seen in a full day clinic was 25 in EECs and 15 in WECs (P < 0.001). Eastern European medical oncologists reported spending a median of 25 min per new consultation compared with 45 min in WECs (P < 0.001). The top two reported barriers in both EECs and WECs to patient care were high clinical volumes and insufficient time for reading. CONCLUSION: The clinical workload of medical oncologists in EECs was substantially higher than in WECs. European health policymakers and educators need to address existing disparities in the workload of medical oncologist, undertake plans for future workforce supply and consider alternative models of care.

Medical oncology workload in Canada: infrastructure, supports, and delivery of clinical care.

Background: In 2000, a Canadian task force recommended that medical oncologists (mos) meet a target of 160-175 new patient consultations per year. Here, we report the Canadian results of a global survey of mo workload compared with mo workload in other high-income countries (hics). Methods: Using a snowball method, an online survey was distributed by national oncology societies to chemotherapy-prescribing physicians in 22 hics (World Bank criteria). The survey was distributed within Canada to all members of the Canadian Association of Medical Oncologists. Workload was measured as the annual number of new cancer patient consults per oncologist. Results: The survey was completed by 782 oncologists from hics, including 58 from Canada. Median annual consults per mo were 175 in Canada compared with 125 in other hics. The proportions of mos having 100 or fewer consults or more than 300 consults per year were 3% (2/58) and 5% (3/58) in Canada compared with 31% (222/724) and 16% (116/724) in other hics (p < 0.001 and p = 0.023 respectively). The median number of patients seen in a full-day clinic was 15 in Canada and 25 in other hics (p = 0.220). Canadian mos reported spending a median of 55 minutes per new consultation; new consultations of 35 minutes were reported in other hics (p < 0.001). Median hours worked per week was 55 in Canada and 45 in other hics (p = 0.200). Conclusions: Although the median annual clinical volume for Canadian mos aligns with recommended targets, half the respondents exceeded that level of activity. Health policymakers and educators have to consider mo workforce supply and alternative models of care in preparation for the anticipated surge in cancer incidence in the coming decade.

Thoracoscopic Retrieval of Unusual Iatrogenic Foreign Bodies.

BACKGROUND: Management of pyothorax and pneumothorax requires aspiration and/or intercostal drainage. CASE CHARACTERISTICS: We present two cases which were complicated by instrument-related events resulting in breakage of needle or intercostal drainage tube resulting in pleural foreign body. INTERVENTION/OUTCOME: The patients were stabilized and the foreign bodies retrieved using thoracoscopic approach. MESSAGE: Thoracoscopy provides a minimally invasive approach to deal with pleural foreign bodies.

Treatment results in advanced stage Hodgkin's lymphoma: a retrospective study.

BACKGROUND: Hodgkin's lymphoma displays distinct epidemiological attributes in Asian population thus making it relevant to study whether there are any differences in treatment outcomes too when treated with current standard of care. AIM: To evaluate the treatment outcomes of de-novo advanced stage HL in adults. MATERIALS AND METHODS: This retrospective study included de-novo advanced stage HL patients (≥15 years) registered at our center from January 2004 to December 2007. Treatment outcomes were measured in terms of response rates, overall survival (OS) and progression-free survival (PFS). Overall and PFS were calculated with Kaplan-Meier methodology and Cox-proportional hazards model was used for multivariate analysis to identify prognostic factors. RESULTS: There were 125 patients (males 77%) who received minimum one cycle of chemotherapy with median age of 32 years (Range 15-65 years). Stage IV disease was seen in (46 patients) 37%; 75% (94 patients) patients had B symptoms. International prognostic score (IPS) ≤4 was seen in 95/112 (85%) patients. ABVD (adriamycin, bleomycin, vinblastine, dacarbazine) chemotherapy was given to 94%. Radiation to residual/bulky sites was given to 36% (45 patients). Response data was available for 112 patients; complete response in 76%; partial response in 10 % and progressive disease in 3 patients. Nineteen deaths (progressive disease-7, toxicity-8, unrelated cause-4) were observed. At median follow-up of 28 months, estimated 5-year OS and PFS were 60% and 58%, respectively. On multivariate analysis, IPS and response to treatment were significant factors for both OS and PFS. CONCLUSIONS: The treatment outcomes in this study are comparable with the published literature with limited follow-up data.

Frequency of bacterial isolates and pattern of antimicrobial resistance in patients with hematological malignancies: A snapshot from tertiary cancer center.

BACKGROUND: Infections are the most important cause of mortality in patients with high-risk febrile neutropenia. Emergence of multi-drug resistant organisms (MDROs) has become a major challenge for hemato-oncologists. Knowledge of the prevalent organisms and their antimicrobial sensitivity can help deciding the empirical therapy at individual centers and allows timely measures to reduce the risk of antimicrobial resistance. AIMS: To evaluate the frequency of bacterial isolates from all the samples and the pattern of bacterial bloodstream infections and incidence of MDROs. SETTINGS AND DESIGN: This is a retrospective analysis from a tertiary care cancer center. MATERIALS AND METHODS: From January to June 2014 information on all the samples received in Department of Microbiology was collected retrospectively. The data from samples collected from patients with hematological cancers were analyzed for types of bacterial isolates and antimicrobial sensitivity. RESULTS: A total of 739 isolates were identified with 67.9% of isolates being Gram-negative. The predominant Gram-negative organisms were Escherichia coli, Psuedomonas spp. and Klebsiella spp. Among the bacterial bloodstream infections, 66% were Gram-negative isolates. MDROs constituted 22% of all isolates in blood cultures. Incidence of resistant Gram-positive organisms was low in the present dataset (methicillin resistant Staphylococcus aureus and vancomycin-resistant enterococci-1.3%). CONCLUSIONS: The analysis reconfirms the Gram-negative organisms as the predominant pathogens in bacteremia seen in patients with hematological cancers. The high frequency of multi-drug resistance in the dataset calls for the need of emergency measures to curtail further development and propagation of resistant organisms.

Paratesticular fibrous hamartoma in an infant.

Fibrous hamartoma of infancy is a rare benign tumour with local infiltration. The lesion is usually found in the upper torso and rarely occurs in the genital region. Diagnosis before surgery is rare, and complete excision is essential to prevent recurrence. We present a case in which fibrous hamartoma of infancy involving the spermatic cord was found. A pre-operative clinical diagnosis could not be made. On inguinal exploration, the tumour could not be dissected away from the testicular vessels, which necessitated an orchidectomy for complete removal. The case is presented due to its rarity and successful management.

Histopathological audit of splenectomies received at a cancer hospital.

BACKGROUND: There are few studies in the literature studying the yield of the diagnostic splenectomy in a suspicious lymphoma case. Moreover, their relevance is limited owing to low number of cases, the use of selection criteria, and the lack of modern ancillary studies. We present a histopathological review of splenectomy specimens referred as a case of lymphoma to our center. MATERIALS AND METHODS: The medical charts and laboratory data on all patients of all splenectomy specimens between the years 2003 and 2008 were reviewed. Morphological and immunohistochemical features were analyzed and the lymphomas were sub-typed in accordance to 2008 WHO Classification of Hematolymphoid Neoplasms. Flow cytometry immunophenotyping available in few cases was correlated. RESULTS: A total of 46 cases studied included splenic marginal zone lymphoma (SMZL) (19 cases), splenic diffuse large B-cell lymphoma (DLBCL) (14 cases), splenic diffuse red pulp B-cell lymphoma (DRP) (five cases), follicular lymphoma (three cases), hairy cell leukemia (HCL) (two cases), HCL variant (HCLv) (1 case), 1 case of hepatosplenic gamma delta T-cell lymphoma (TCL), and 1 cases of TCL (not otherwise specified). CONCLUSIONS: Predominantly splenic lymphoma is a biologically heterogeneous entity, ranging from low-grade SMZL to high-grade DLBCLs. TCLs constituted only 4% of all our cases. DRP, HCL, and HCLv have similar diffuse red pulp patterns of splenic involvement and are differentiated based on flow cytometric immunophenotyping. We had a large number of splenic DLBCL and none of these involved bone marrow (BM), while all other lymphoma subtypes had BM involvement (stage IV disease). Morphological and immunophenotypic (immunohistochemistry and flow cytometry) features of BM and splenectomy specimen need to be correlated to differentiate these rare though similar-looking entities with overlapping features.

Immunophenotyping of mature T/NK cell neoplasm presenting as leukemia.

INTRODUCTION: Mature T/NK cell lymphomas (MTNKL) presenting as leukemia are rare and show considerable overlapping of clinical, morphological and immunophenotypic features. AIM: Critical analysis of the morphology and immunophenotypic profile of MTNKL. MATERIALS AND METHODS: We reviewed 380 consecutive cases of mature lymphoid neoplasm that presented as leukemia and were diagnosed on morphology and immunophenotyping of bone marrow and/or peripheral blood samples. RESULTS: Peripheral blood and bone marrow involvement was seen in all cases. MTNKL constituted 4% (nine cases) of all mature lymphoid neoplasms presenting as leukemia. It included four cases of T-large granular leukemia (T-LGL), two of T-cell prolymphocytic leukemia small cell variant (T-PLL), two of adult T-cell leukemia/lymphoma (ATLL) and one of primary cutaneous gamma delta T-cell lymphoma (PCGDTCL). T-LGL revealed CD4-/CD8+ phenotype in three, and CD4+/CD8+ phenotype in one case. CD56 was absent in all the cases of T-LGL. One case of T- PLL small cell variant showed CD4+/CD8- phenotype, while the other revealed CD4-/CD8+ phenotype. Both cases of ATLL showed CD4+/CD8+/CD25+ phenotype. The single case of PCGDTCL showed CD4-/CD8- phenotype pattern. CD3 and CD5 were expressed in all MTNKL. CD7 was absent in three cases of T-LGL. TCRalpha/beta was performed in three cases of T-LGL and was positive in all. TCRalpha/beta was also seen in both the cases of T-PLL small variant. However, TCRalpha/beta was seen in the single case of PCGDTCL. CONCLUSION: Mature nodal T/NK cell neoplasms are rare and MTNKL presenting as leukemia are even rarer. There is an overlap between the immunophenotypic profiles of different MTNKL subtypes and elaborate T/NK cell panels are required for their evaluation.

Presence of paraneuronal pseudobranchial neurosecretory system in the gill region of two air-breathing clupeids, Notopterus chitala and Notopterus notopterus.

The pseudobranchial neurosecretory system (PNS) is a system of neurosecretion observed in certain groups of teleosts, which are air-breathing or known to tolerate low oxygen tension in the surrounding water. Like other neuroendocrine cells of gill, cells belonging to this system have also been observed to have a role in condition of hypoxia. Uniformly found in all catfish species, the system was reported to be present in few non-catfish groups also, viz.-Atheriniformes, Channiformes (Devi, 1987), Perciformes, and Clupeiformes (Srivastava et al., 1981; Gopesh, 1983). In an attempt to study the structure and organization of the pseudobranchial neurosecretory system in non-catfish species of teleost, present investigation was undertaken in two species of Notopterus, viz. Notopterus chitala and Notopterus notopterus. The histological observations, using neurosecretion specific stains, undertaken on two clupeids are reported and the findings are discussed in the light of association of PNS with Carotid gland-a structure of intermediate stage in the process of transformation of pseudobranch into the carotid labyrinth, in course of evolution and also the air-breathing habit of the fish.

Management and clinical outcome of sinonasal teratocarcinosarcoma: single institution experience.

PURPOSE: To study the outcome of patients with sinonasal teratocarcinosarcoma treated at a single institution. METHODS: We reviewed the medical records of 22 patients with histopathologically proven sinonasal teratocarcinosarcoma diagnosed during the period 1993-2007. Treatment was completed in 16 patients. RESULTS: Fourteen patients underwent surgery (six received craniofacial resection, four open surgery and four endoscopic resection); this was followed by radiation therapy with or without chemotherapy in 11 patients. Two patients received chemoradiation as the definitive treatment. At median follow up in surviving patients of 34 months (range one to 180 months), only five were controlled. Disease recurred in 11 patients, with a median time to recurrence of seven months. The two-year disease-free survival rate and the overall survival rate were 28 and 46 per cent, respectively. CONCLUSION: Sinonasal teratocarcinosarcoma appears to be an aggressive disease, with the majority of patients suffering locoregional failure. Multimodality treatment, in the form of a combination of surgery, radiation therapy and chemotherapy, appears to be the optimal approach.

Non-Hodgkin's lymphoma of Waldeyer's ring in children: outcome using chemotherapy and involved field radiotherapy.

AIM: To evaluate the prognostic factors and treatment outcome of children with non-Hodgkin's lymphoma (NHL) of Waldeyer's ring treated at a single institution. MATERIALS AND METHODS: Thirty-two children with NHL of Waldeyer's ring treated at our institute between January 1990 and December 2001 were included in this analysis. The median age at presentation was 14 years, and most of the patients (87%) were boys. The most common histological subtype was diffuse large B-cell lymphoma (75%), 25% patients had stage I and 75% had stage II disease. Treatment comprised a combination of chemotherapy and radiotherapy in most of the patients (75%). Among these patients, 71% received a radiotherapy dose of > or = 45 Gy. RESULTS: After a median follow-up of 45 months, the 5-year disease-free and overall survival rates were 76.5 and 83.2%, respectively. Age > 10 years (P = 0.032), bulky tumours (P = 0.001) and the presence of B-symptoms (P = 0.004) had a negative influence on disease-free survival. Patients treated with a combination of chemotherapy and radiotherapy had a better outcome than patients treated with chemotherapy alone (disease-free survival: 87.1% vs 56.2%, P = 0.056). The complete response (P = 0.003), disease-free survival (P = 0.001) and overall survival (P = 0.001) rates were significantly better for patients receiving a radiotherapy dose > or = 45 Gy. CONCLUSION: The age at diagnosis, the size of the tumour, and the presence of B-symptoms significantly influenced the outcome of children with NHL of Waldeyer's ring in this study. A combined modality treatment, comprising chemotherapy and radiotherapy, resulted in a satisfactory outcome in patients with this rare neoplasm.

Fludarabine in lymphoproliferative malignancies: a single-centre experience.

BACKGROUND: Fludarabine has been reported to be an effective drug for the treatment of chronic lymphocytic leukaemia (CLL) and indolent lymphomas. However, its safety and efficacy in Indian patients has not been studied. We retrospectively analysed our experience with fludarabine in low grade lymphomas and CLL. METHODS: The records of all patients with low grade lymphoma or CLL who received fludarabine between April 1999 and November 2006 were analysed. Response evaluation was done as per the National Cancer Institute-Working Group guidelines for CLL and International Workshop criteria for non-Hodgkin lymphomas, respectively, in those patients who received at least 3 cycles of fludarabine. Toxicity was graded as per the common terminology criteria for adverse events, version 3.0. Median event-free survival was obtained using Kaplan-Meier survival analysis. RESULTS: Forty-seven patients were included in the study and 189 cycles were administered (median: 4 cycles per patient). Sixteen patients had a treatment delay, 14 due to myelosuppression. Twenty-five patients had low grade lymphoma and 22 had CLL. The response was evaluable in 22 patients with low grade lymphoma and 20 with CLL. The overall response rate for CLL was 100% in those treated upfront (n=9) and 55% in those with relapsed disease (n=11). The overall response rate for low grade lymphoma was 88% (63% complete remission) in untreated patients and 79% (43% complete remission) in those with relapsed disease. Common adverse events were myelosuppression and infection. Two patients died of sepsis and 4 due to disease progression on treatment. Median event-free survival for patients treated upfront with fludarabine was 31.4 months. CONCLUSION: In our patient population, response to fludarabine is similar to that in the published literature. Our patients had a higher frequency of haematological toxicity.

The effect of short-term intensive chemotherapy on reactivation of tuberculosis.

BACKGROUND: Various malignancies and cytotoxic chemotherapy have been proposed to increase the risk of reactivation of tuberculosis. Available literature to support this observation is still conflicting. There is scarcity of data from countries with rampant tubercular infection, such as India, in this regard. DESIGN AND METHODS: In the present retrospective analysis, patients with high-grade non-Hodgkin's lymphoma with past history of tuberculosis and have had adequate antitubercular therapy were identified from a Lymphoma Group study. These patients were followed up during cytotoxic chemotherapy and later to assess the risk of reactivation. RESULTS: A cohort of eight patients with past history of tuberculosis was selected from 141 patients of high-grade non-Hodgkin's lymphoma. The median age was 33.5 years (range, 24-53 years). Median duration between completion of antitubercular treatment and diagnosis of lymphoma was 5 years (range, 1.5-10 years). All patients received cyclical cytotoxic chemotherapy. The median duration of follow up after completion of chemotherapy was 5 years (range, 10 months to 5 years). None of these patients developed reactivation of tuberculosis. CONCLUSION: Cyclical chemotherapy for non-Hodgkin's lymphoma does not lead to reactivation of tuberculosis.

Forme fruste choledochal cyst.

Two girls presenting with features of pancreatitis were diagnosed to have minimal dilatation of extra hepatic biliary duct (EHBD) associated with pancreatico-biliary maljunction (PBMJ). A high degree of suspicion is required to diagnose this condition that has been termed Forme fruste choledochal cyst (FFCC). Both did well with pancreatico-biliary disconnection procedure and reconstruction of biliary channel using enteric conduit.
