Fifty-four episodes of Xanthomonas maltophilia infection were observed in 52 HIV-infected patients out of 2062 assessed (2.52%) over a 6-year period: sepsis/ bacteraemia in 44 cases, lower airways infection in 5 cases, urinary tract infection and pharyngitis in 2 cases each, and lymph node involvement in one patient. X. maltophilia represented the fourth most common non-mycobacterial bacterial pathogen responsible for bacteraemia in HIV-infected patients: 44 cases out of 721 diagnosed (6.1%). When compared with non-typhoid Salmonella spp. bacteraemia, an increased risk to develop X. maltophilia disseminated infection was seen according to the progression of HIV-related immunodeficiency, the occurrence of leukopenia-neutropenia, central venous catheterization, previous antibiotic and/or corticosteroid treatment, and hospitalization. In 3 patients suffering from concurrent AIDS-related disorders, X. maltophilia infection contributed to death, while a recurrence occurred in 2 cases only. Due to the poor antimicrobial susceptibility of this pathogen (also confirmed in our series), X. maltophilia bacteraemia associated with advanced HIV infection and concurrent risk factors, may represent a potentially severe disease.

Background. Dedifferentiated chondrosarcomas (DDCSs) are highly malignant tumors with a dismal prognosis and present a significant challenge in clinical management. Methods. In an IRB approved retrospective protocol, we identified 72 patients with DDCS treated at our institution between 1993 and 2017 and reviewed clinicopathological characteristics, treatment modalities, and outcomes to analyze prognostic factors. Results. Femur (44.4%), pelvis (22.2%), and humerus (12.5%) were most commonly involved sites. Twenty-three patients (31.9%) presented with distant metastasis, and 3 (4.2%) of them also had regional lymph node involvement. The median overall survival (OS) was 13.9 months. On multivariate analysis, pathological fracture, larger tumor size, lymph node involvement, metastasis at diagnosis, extraosseous extension, and undifferentiated pleomorphic sarcoma component correlated with worse OS, whereas surgical resection and chemotherapy were associated with improved OS. For progression-free survival (PFS), pathological fracture and metastasis at diagnosis showed increased risk, while chemotherapy was associated with decreased risk. Among patients who received chemotherapy, doxorubicin and cisplatin were significantly associated with improved PFS but not OS. Among patients without metastasis at diagnosis, 17 (34.7%) developed local recurrence. Thirty-one (63.3%) developed distant metastases at a median interval of 18.1 months. On multivariate analysis, R1/R2 resection was related with local recurrence, while macroscopic dedifferentiated component was associated with distant metastasis. Conclusions. The prognosis of DDCS is poor. Complete resection remains a significant prognostic factor for local control. Chemotherapy with doxorubicin and cisplatin seems to have better PFS. More prognostic, multicenter trials are warranted to further explore the effectiveness of chemotherapy in selected DDCS patients.

205 Background: Commonly used tools for predicting the risk of pelvic lymph node involvement (LNI) in prostate cancer often do not incorporate information on the percentage of positive biopsy cores (PPB). To better inform the use of elective nodal irradiation in the definitive treatment of prostate cancer, we examined the association between PPB and risk of pathologic pelvic LNI in men with prostate cancer who underwent radical prostatectomy (RP). Methods: We identified 109,577 men from the National Cancer Database who were diagnosed in 2010-2015 with cN0M0 prostate cancer, had 6-24 cores sampled at biopsy, and underwent RP with pathologic nodal evaluation. Multivariable logistic regression was used to examine the association between PPB and the likelihood of having ≥1 positive pelvic lymph node, adjusting for other known clinicopathologic prognostic variables. Results: Overall, 4.0% (4,340) of the cohort was found to have pelvic LNI at the time of RP. Higher PPB was associated with an increased risk of pelvic LNI (adjusted odds ratio [AOR] 1.75 for 25.1-50.0% PPB, 2.63 for 50.1-75.0% PPB, and 4.49 for 75.1-100.0% PPB vs. ≤25.0% PPB, all P<0.001). Notably, men with Gleason 8 disease and ≤25.0% PPB only had a 3.6% risk of pelvic LNI, whereas men with Gleason 9-10 disease and 75.1-100.0% PPB had a 32.6% risk (Table). Other factors associated with the likelihood of pelvic LNI included a higher biopsy Gleason score (AOR 1.43 for Gleason 8 and 2.84 for Gleason 9-10 vs. Gleason 4+3, both P<0.001), more advanced clinical tumor stage (AOR 1.48 for cT2, 1.97 for cT3, and 3.87 for cT4 vs. cT1, all P<0.001), and a higher PSA (AOR 1.90 for 10.0-19.9 ng/mL, 2.40 for 20.0-39.9 ng/mL, and 2.60 for ≥40.0 ng/mL vs. <10.0 ng/mL, all P<0.001), but not more advanced age (AOR 0.98 for >62 years [median] vs. ≤62 years, P=0.59) or black vs. white race (AOR 0.99, P=0.92). Conclusions: There was a statistically significant and clinically relevant association between increasing PPB and a higher risk of pelvic LNI. As the ongoing RTOG 0924 randomized trial matures, clinicians should consider incorporating information on PPB in determining which patients with prostate cancer may benefit from receiving radiation therapy to the pelvic lymph nodes.

Carcinoma Stomach

Background: Carcinoma stomach, a major killer cancer all over the world, is still presenting late in developing countries due to delay in early diagnosis, lack of awareness, infrastructure etc. Objectives: To establish the importance of preoperative evaluation on operability of carcinoma stomach. Methods: Sixty clinically and histopathologically diagnosed ca stomach cases who underwent surgery in department of Bangabandhu Sheikh Mujib Medical University, Dhaka, and Dhaka Medical College Hospital, Dhaka in 2011 were assessed with clinical picture, investigations, preoperative evaluation and peroperative findings were recorded. Z test for proportion was used to assess clinical decision predictability with a p value of :s;0.05 as significant. Results: Male (73.33%) predominant with 2.75:1 male:female ratio was observed. Mobility, fixity and abdominal lymphadenopathy were not well detected through clinical assessment (p=0.001) while ascites, metastasis and Shelf of Slummer were similar in both clinical and operative finding. The endoscopy of upper GIT finding gave a unique picture as the findings were almost same as were found during operation. USG detected a lesser proportion of the clinical condition compared to peroperative condition whereas CT performed better than the USG except for the lesion detection. Though Computed Tomography (CT) detected higher percentage of lesion, metastasis, ascites and lymph node involvement compared to ultrasonogram (USG), it was significantly higher only for lesion detection (p=0.002) and lymph node involvement (p=<0.001). In the similar manner USG assessment of lesion detection (p=<0.001) and lymph node involvement (p=0.003) was significantly low compared to operative finding. When we looked between CT and operative finding only lesion detection was significantly low (p=0.01) indicating CT to be most effective predictor of clinical picture for operative decision. Preoperative plan were mostly not in accordance with peroperative decision except for total gastrectomy. Conclusion: The study indicates weakness in clinical detection and pre-operative plan compared to per-operative finding. Hence combination of clinical feature and investigation tools especially endoscopy of upper GIT combined with CT is recommended to predict a better operative decision.
