The purpose of this retrospective study of 20 client-owned cats was to describe the clinical signs, surgical interventions, histological features, stage and treatments of primary lung tumors removed by surgical excision, and to determine which factors significantly influence survival. Any cat that underwent surgical resection of a primary lung tumor between 2000 and 2007 was included in the study. Patient records were reviewed and signalment, clinical signs, preoperative diagnostics, surgical findings and histopathological results recorded. Histological reports were reviewed and scored using World Health Organization criteria. The Kaplan–Meier test was used to evaluate each potential prognostic factor with survival. Twenty cats met the inclusion criteria. The presence of clinical signs (such as dyspnea) at the time of diagnosis ( P = 0.032), pleural effusion ( P = 0.046), stage M1 ( P = 0.015), and moderately and poorly differentiated tumors on histopathology ( P = 0.011) were factors that were significantly correlated with reduced survival times. The median survival time of the 20 cats was 11 days. Cats presenting with no clinical signs had a median survival time of 578 days post-surgery vs 4 days post-surgery when presented with clinical signs. Cats staged T1N0M0 lived longer than cats at other stages ( P = 0.044). Of the cats that survived to the time of suture removal, median survival time was 64 days. The results indicate that the presence of clinical signs, pleural effusion, moderately and poorly differentiated tumors on histopathology, evidence of metastasis and any stage beyond T1N0M0 are negative prognostic indicators for cats with primary lung tumors. The findings demonstrate that cats that presented with clinical signs, pleural effusion, any stage other than T1N0M0, or moderately and poorly differentiated tumors on histopathology had a poor prognosis. Therefore, extensive preoperative diagnostics, including computed tomography scans, should be performed before considering surgical intervention in these cats. These findings may be used to guide therapeutic decision-making in cats diagnosed with primary lung tumors.

Primary Tumors

The current management of dogs with spinal canal neoplasia in a large veterinary institution was evaluated. Postoperative survival time and prognostic indicators for survival were examined. Spinal neoplasms in dogs and humans also were compared. Thirty-seven cases with histologically confirmed spinal tumors were included in the study. The cervical region was affected most commonly, and 23 (62%) of 37 cases had extradural tumors. A hemilaminectomy or a dorsal laminectomy was performed in each case; three cases received adjuvant treatment. Twelve (32%) cases were euthanized at the time of surgery, and two died immediately after surgery. One dog was euthanized 20 days after surgery because of persistent clinical signs. Twenty-two cases were followed postoperatively; nine different types of primary tumors were confirmed by histological examination of tissue specimens from these 22 cases, and three cases had metastatic lesions. The median survival time of these 22 cases was 240 days. Twelve (32%) of the 37 cases had nerve-sheath tumors; the median survival time for these 12 cases was 180 days. No prognostic indicators were identified. However, median survival times of cases with benign versus malignant tumor types were 1,410 days and 180 days, respectively (p of 0.07). Four cases each had a myxoma/myxosarcoma, a tumor previously unreported in the spinal canal in dogs.

Response To Chemotherapy

This was a multi-institutional retrospective study evaluating the outcome and clinical parameters associated with the postoperative prognosis of 36 cats with splenic mast cell tumors treated with splenectomy. Clinical parameters reviewed included signalment, clinical history, results of staging tests, surgical variables, administration of blood products, presence of metastasis, postoperative complications, administration of chemotherapy postoperatively, chemotherapy protocol, and response to chemotherapy. Overall median survival time was 390 days (range, 2–1737 days). Administration of a blood product (P < .0001), metastasis to a regional lymph node (P = .022), and evidence of either concurrent or historical neoplasia (P = .037) were negatively associated with survival. Response to chemotherapy (P = .0008) was associated with an improved median survival time. Larger-scale prospective studies evaluating different chemotherapy protocols are required to elucidate the discrepancy between lack of survival benefit with administration of chemotherapy and improvement in survival time with positive response to chemotherapy.

Abstract Although the presence or absence of somatic mutations in the immunoglobulin variable region (IgVH) genes in chronic lymphocytic leukemia (B-CLL) identifies subtypes with very different prognoses, the assay is technically complex and unavailable to most laboratories. CD38 expression has been suggested as a surrogate marker for the 2 subtypes. IgVHmutations and CD38 expression in 145 patients with B-CLL with a long follow-up were compared. The 2 assays gave discordant results in 41 patients (28.3%). Multivariate analysis demonstrated that Binet stage,IgVH mutations and CD38 were independent prognostic indicators. Median survival time in patients whose cells had unmutated IgVH genes and expressed CD38 was 8 years; in those with mutated IgVHgenes not expressing CD38, it was 26 years. For those with discordant results, median survival time was 15 years. Thus, although CD38 expression does not identify the same 2 subsets as IgVHmutations in CLL, it is an independent risk factor that can be used with IgVH mutations and clinical stage to select patients with B-CLL with the worst prognoses. Using cryopreserved cells taken at intervals during the course of the disease, however, changes of CD38 expression over time were demonstrated in 10 of 41 patients. Causes of the variation of CD38 expression require further study. Additional prospective studies are required for comparing CD38 expression with other prognostic factors and for taking sequential measurements during the course of the disease.

A retrospective study was performed of 17 dogs and seven cats with various stages of thymoma treated with radiation alone or as an adjunctive therapy. Analysis revealed an overall response rate of 75% (15/20 evaluable cases). Partial (i.e., >50% reduction in tumor size) and complete (i.e., no detectable tumor) responses were included. Complete responses were rare (4/20). Three of five animals with stable disease (i.e., <50% change in tumor size) had improvements in clinical signs, despite lack of measurable response. A median survival time of 248 days (range, 93 to 1,657+ days) was achieved in dogs, and a median survival time of 720 days (range, 485 to 1,825+ days) was achieved in cats. Radiation therapy appears to be useful in the management of invasive thymomas in dogs and cats.

The prevalence of cardiomyopathy in Irish wolfhounds was evaluated by retrospective review of the results of cardiovascular examinations carried out in 500 dogs presented for veterinary services at the author's practice. Abnormalities were found in 209 (41.8%) of the dogs examined. Dilated cardiomyopathy (DCM) was diagnosed in 121 (24.2%) of the dogs and was accompanied by atrial fibrillation in 106 dogs. Seventeen dogs were suffering from advanced congestive heart failure (CHF), and 55 dogs were suffering from mild to moderate CHF as a result of DCM. Congestive heart failure was most commonly characterized by mild to severe pleural effusion due to right-sided heart failure in addition to pulmonary edema. Rhythm disturbances without evidence of DCM were detected in 48 dogs. Forty dogs had echocardiographic abnormalities without signs of DCM. Soft to moderate mitral regurgitations were diagnosed in 13 (2.6%) of these 40 dogs examined. In 39 dogs that died as a result of DCM, the median survival time from the time of diagnosis was 5.1 months, and in 59 dogs with DCM that are still alive, the median survival time is 15.7 months.

Large Cell Lymphoma

Objectives Lymphoma is a common and clinically important malignancy in cats. Development of a second malignancy has been reported previously in 7–14% of cats with small-cell gastrointestinal (GI) lymphoma. The aim of our study was to describe the incidence, clinical signs, clinicopathologic data, response to therapy and outcomes in cats diagnosed with large-cell lymphoma following treatment for small-cell GI lymphoma. Methods Medical records from a single referral specialty hospital were reviewed for all cats with lymphoma diagnosed between 2008 and 2017. The cases with a diagnosis of small-cell GI lymphoma followed by a diagnosis of any large-cell lymphoma and complete outcome data were selected for further review. Results Seven hundred and forty cats with a diagnosis of lymphoma were identified. Twelve cats (12/121) treated for small-cell GI lymphoma followed by a diagnosis of any anatomic form of large cell lymphoma were identified. Nine cats met the study inclusion criteria and were used in analyses. Mean event-free survival time from small-cell GI lymphoma diagnosis until diagnosis of large-cell lymphoma was 543 days, with a median survival time of 615 days. Mean event-free survival time from large-cell lymphoma to death was 55 days, with a median survival time of 24.5 days. Hematocrit, albumin and total protein were significantly decreased when cats developed large-cell lymphoma compared with their values at the time of small-cell lymphoma diagnosis. Conclusions and relevance Large-cell lymphoma occurred in 9.9% (12/121) of cats treated for small-cell GI lymphoma. Feline practitioners should include large-cell lymphoma on their list of differential diagnoses in cats diagnosed with small-cell GI lymphoma developing weight loss, anemia, hypoalbuminemia and hypoproteinemia.

7079 Myelodysplastic syndromes (MDS) are a diverse group of clonal stem cell disorders characterized by bone marrow failure, dysmyelopoiesis and peripheral cytopenias and affecting predominantly an elderly population. The International Prognostic Scoring System (IPSS) incorporates the number of peripheral cytopenias, percentage of bone marrow blasts and chromosomal abnormalities and assigns a score to predict survival and risk of disease progression to AML. Using the extensive MDS database at the University of Massachusetts we analyzed survival time in relation to IPSS scoring and also its various individual components, i.e. blast percentage, number of cell lines involved and the number of karyotype abnormalities in 1,200+ patients. The overall median survival time in 1,424 MDS patients as a group was 2.9 years. IPSS low group had the longest median survival time of 7.5 years with IPSS Int-1 3.6 years. There was minimal difference in the median survival time between IPSS Int-2 and IPSS high risk group 1.2 and 1.1 years respectively. These results were significant for a P value of <0.0001. The median survival time for blasts <5% was 5.3 years and blast 5–10% was 1.7 years. Interestingly, there was minimal survival difference between median survival time for blasts 11–20% and blasts >20% showing 1.2 years and 1.3 years respectively. Again, these results were significant for a P value of <0.0001. The median survival time for the number of cytopenias involved was also calculated with 0, 1, 2 and 3 numbers of cytopenias showing 6.4 years, 4.4 years, 2.6 years and 1.8 years respectively, with P value of <0.0001. The median survival time for normal karyotype versus one or two karyotype abnormality was 4.9 years, 2.6 years and 2.4 years respectively. Three or more karyotype abnormalities showed a median survival time of 0.8 years. The P value was again significant (<0.0001). Our results not only validate the prognostic value of IPSS scoring system as a whole but also its various individual prognostic indicators. No significant financial relationships to disclose.

Medical Problem

Background: Malignant pleural effusion is a common medical problem in patients with cancer. The survival of patients with malignant pleural effusion is generally poor. The objectives of our study were to reveal possible prognostic factors of malignant pleural effusion.Methods: Fifty-three consecutive patients, 34 male and 19 female patients of malignant pleural effusion diagnosed by pleural fluid positive for malignant cytology and/or pleural tissue positive for malignancy by thoracoscopy biopsy. Performance status by the Eastern Cooperative Oncology Group (ECOG) score and LENT score was calculated at the time of diagnosis. Median survival time was calculated using Kaplan-Meier analysis curve. Survival time was defined as the time from diagnosis to death or the last follow-up.Results: Most common cause of malignant pleural effusion was lung carcinoma 46 (86.79%). Adenocarcinoma was the most common 31 (58.5%) followed by NSCLC 10 (18.0%). Low, moderate and high-risk LENT score was found in 3 (5.7%), 35 (66%) and 15 (28.3%) respectively.  The median survival time of pleural fluid sugar less than 20 were 3 months. The median survival time of LENT low, medium and high risk was 12 months, 5.2 months and 2.5 months respectively. The median survival time of patients with ECOG score of 1 and 4 was 6.5 months and 1 month respectively. Patients with bilateral pleural fluid had a mean survival time of 2 months.Conclusions: Adenocarcinoma lung is the most common etiology of malignant pleural effusion. The median overall survival time was 4 months. Higher ECOG score and LENT score are associated with shorter survival time.

Abstract OBJECTIVE To retrospectively analyze the therapeutic effects of radiotherapy with concomitant and adjuvant temozolomide versus radiotherapy with concomitant temozolomide alone for pediatric diffuse intrinsic pontine glioma (DIPG), and to evaluate the value of temozolomide in the treatment of pediatric DIPG. METHODS The clinical data of children with confirmed DIPG in Guangdong Sanjiu Brain Hospital between January 1, 2010 and December 30, 2019 were collected. The inclusive criteria included (1) receiving a total radiotherapy dose of 54 Gy in 27 fractions, (2) treated with concomitant temozolomide chemotherapy, and (3) with or without adjuvant temozolomide chemotherapy. RESULTS A total of 82 pediatric patients were eligible for the study, with a median age of 7 years (range 2–16 years). The median follow-up was 8.6 months (range 2–28 months) and the median survival time was 9.4 months. The median survival time of 66 patients treated with radiotherapy with concomitant and adjuvant temozolomide was 9.8 months, longer than 7.5 months of the other 16 patients treated with radiotherapy with concomitant temozolomide alone, with statistical differences (P=0.010). Moreover, bevacizumab and nimotuzumab didn’t bring survival benefits to patients with disease recurrence or progression. Hematological toxicity (Grade IV) was not found. CONCLUSION Radiotherapy with concomitant and adjuvant temozolomide prolongs the survival time of children with DIPG.
