Although pathologic response to neoadjuvant chemotherapy is highly correlated with survival among patients with osteosarcoma, there are currently no established molecular markers to predict response to chemotherapy. The objective of this study was to investigate the relationship of P16 expression in pretreatment osteosarcoma tumors to pathologic necrotic response after neoadjuvant chemotherapy. A tissue microarray was created from paraffin-embedded pretreatment biopsy specimens of 40 patients with osteosarcoma. Immunohistochemistry was performed with commercially available P16 monoclonal mouse antibody. Expression of P16 was defined as nuclear staining in 30% or greater of cells. Percent tumor necrosis was measured in postchemotherapy resection specimens per established protocols, and 90% or greater tumor necrosis was considered "good." Data were abstracted on age, sex, tumor site, and histologic subtype. Univariate and multivariate analyses were performed. The median age was 15 years, 52% were female, and 35% of tumors were located in the femur. P16 expression was present in 62%. Median posttreatment tumor necrosis was 90%, and 55% of patients experienced "good" chemotherapy response (≥90% necrosis). On univariate analysis, P16 expression correlated positively with median percent necrosis and "good" chemotherapy response (P = .004 and .003, respectively). On logistic regression analysis, P16 expression was independently associated with chemotherapy response after controlling for age, subtype, sex, and location (odds ratio, 43.5; 95% confidence interval, 2.64-708.9; P = .008). In summary, immunohistochemical expression of P16 significantly correlates with chemotherapy response in osteosarcoma. P16 expression may be a useful biomarker to guide treatment selection.
FIFTH ANNUAL MEETING OF POLISH PATHOLOGISTS IN AMERICA USCAP 2016, SEATTLE
Dear all polish pathologists in America I think it is time to finally meet at next USCAP in Seattle. I was thinking about Saturday March 12th 2016 at 7 pm next to USCAP registration desk. Anyone interested please be there and we will go for some drinks and food. Elvis will be there.

Chicago Orthopaedic Pathology Society was formed to connect and discuss interesting bone and soft tissue cases between bone pathologists from Chicago and other places.
The main idea is to exchange knowledge, science and expertise in collegial and friendly athmosphere using telepathology.
Please join us for our meetings if you have any interesting bone and sofdt tissue cases.

In July I was visiting Rizzoli Orthopedic Institute Bologna, Italy. I've had great opportunity to see very interesting bone and soft tissue cases. I would like to thank Drs. Marco Gambarotti, Franco Bertoni and Daniel Vanel for sharing with me their knowledge and experience.
Bologna is great town known for friendly people and best food. I would advise to have best gelato at cremeria funivia on Piazza Cavour and best food at Drogheria della Rosa on Via Cartoleria.
