Survival in patients with intermediate or high grade non-Hodgkin's lymphoma: meta-analysis of randomized studies comparing third generation regimens with CHOP
In patients with intermediate or high grade non-Hodgkin lymphoma (NHL), third generation chemotherapy regimens have been introduced to improve survival in comparison with the standard CHOP regimen. However, most studies have found no difference between these two treatments. We conducted a meta-analysis to assess the effectiveness of third generation regimens as compared with CHOP. Our study included the randomized controlled trials published in English from 1970 to 1999. After a Medline search, 5 trials were found to meet our inclusion criteria. A total of 1982 patients, that were enrolled in these trials, were included in the survival meta-analysis. Our methodology retrieved patient-level information from all of these subjects; survival up to 9 years after randomization was compared between the two treatment options. The results of our meta-analysis showed that, in comparison with CHOP, third generation chemotherapy did not prolong survival at levels of statistical significance (chi-square by log-rank test = 1.44, P = 0.23). The relative death risk for third generation regimens vs. CHOP was 0.92 (95%CI: 0.80 to 1.06;Pâ =â0.26). We conclude that, on the basis of our meta-analysis, third generation regimens do not confer any survival benefit to patients with intermediate or high grade NHL as compared with CHOP. © 2001 Cancer Research Campaign http://www.bjcancer.co
Criptorquidia, fisiologĂa, patologĂa asociada, clasificaciĂłn, examen fisico y controversias sobre el tratamiento
El testĂculo no descendido o criptĂłrquido es aquel que no se localiza en la regiĂłn inferior del escroto o que luego de descender con maniobras manuales al escroto no permanece en esta localizaciĂłn. La importancia de la ubicaciĂłn normal del testĂculo es reconocida desde hace siglos, en la Edad Media para confirmar que el papa elegido era un hombre completo, se evaluaba si tenia los testĂculos ubicados normalmente: âtestĂculos habet, et bene pendentesâ1 . Es la anomalĂa congĂ©nita mas frecuente en el varĂłn y un reconocido factor de riesgo asociado a infertilidad y cĂĄncer testicular en la adultez. La mayorĂa de las veces la etiologĂa es desconocida. Probablemente en estos casos, su origen sea multifactorial, pudiendo tener un rol agentes ambientales que interactuarĂan con factores genĂ©ticos propios provocando la disrupciĂłn del proceso de descenso normal del testĂculo. Desde hace dĂ©cadas existen dos modalidades terapĂ©uticas, el tratamiento hormonal y/o la orquidopexia. Los primeros reportes sobre estos tratamientos son de aproximadamente el año19302,3. Desde entonces, han sido publicados mĂĄs de 3300 artĂculos. Sin embargo, a pesar de la profusa literatura al respecto, aĂșn existen controversias sobre la conducta terapĂ©utica mĂĄs adecuada. Esto se debe en parte a la falta de estudios bien diseñados a largo plazo que permitan obtener conclusiones estadĂsticamente valederas. Actualmente, el tratamiento Ăłptimo para la criptorquidia es un tema importante de debate en los foros internacionales. El objetivo de esta revisiĂłn es actualizar la fisiopatologĂa y la etiopatogenia, y discutir las evidencias a favor o en contra de las modalidades terapĂ©uticas actuales.Fil: Vaiani, Elisa.

Development of a prognostic score to predict response to Yttrium-90 radioembolization for hepatocellular carcinoma with portal vein invasion
Background & Aims: Yttrium-90 transarterial radioembolization (TARE) has shown promising efficacy in the treatment of patients with hepatocellular carcinoma (HCC), associated with portal vein tumor thrombus (PVTT). The aim of this study is to identify prognostic factors for survival in patients with HCC and PVTT undergoing TARE, and build a prognostic classification for these patients.
Methods: This is a single center retrospective study conducted over six years (2010-2015), on consecutive patients undergoing TARE. Patients were included if they met the following criteria: presence of at least one measurable HCC, presence of PVTT not occluding the main portal trunk, absence of extrahepatic metastases, Child-Pugh score within B7, Eastern Cooperative Oncology Group performance status 0-1. Uni- and multivariable analysis was used to explore the variables that showed an independent relationship with survival. A prognostic score was then derived, and three prognostic categories were identified.
Results: A total of 120 patients were included in the study. Median overall survival (OS) was 14.1 months (95% CI 10.7-17.5) and median progression-free survival (PFS) was 6.5 months (95% CI 3.8-9.2). The only variables independently correlated with OS were bilirubin, extension of PVTT and tumor burden. Three prognostic categories were identified: favourable prognosis (0 points), intermediate prognosis (2-3 points) and dismal prognosis (>3 points). Median OS in the three categories was 32.2 months, 14.9 months and 7.8 months respectively (p <0.0001). PFS (p = 0.045) and the risk of liver decompensation (p <0.0001) also significantly differed along the same prognostic categories.
Conclusions: Radioembolization with Yttrium-90 is an effective therapy for patients with HCC and PVTT. The proposed prognostic stratification may help to better identify good candidates for the treatment, and those for whom TARE may be futile.
Lay summary: Yttrium-90 transarterial radioembolization (TARE) is a microembolic procedure that minimizes alterations to hepatic arterial flow, and thus can be safely performed in patients with hepatocellular carcinoma (HCC) and portal vein tumor thrombus (PVTT). In this study, we retrospectively evaluated the independent predictors of long-term outcomes in patients with HCC and PVTT treated with TARE. Bilirubin level, extension of PVTT and tumor burden were independently related to post-treatment survival: the combination of these factors allowed us to build a prognostic stratification that may help to better identify good candidates for the treatment, and those for whom TARE may be futile.

Integrated strontium isotope stratigraphy and biochronology in the upper Pliocene and Pleistocene of DSDP Site 132 (western Mediterranean)
Planktonic foraminifer shell samples from the upper Pliocene and Pleistocene sequence of the DSDP Site 132 (Tyrrhenian Sea) provide evidence for a general increasing trend in the seawater 87Sr/86Sr isotopic ratios and suggest the applicability of the high-resolution oceanic curves of Sr isotope variations in the land-locked Mediterranean basin. However, a possible exception is detected in the interval between 0.8 and 0.3 Ma, where ratios lower than coeval oceanic values are recognised. The planktonic foraminiferal biostratigraphy and biochronology of this site are consistent with previous Mediterranean studies. The first occurrences (FOs) of Beella digitata, Orcadia riedeli and Globigerina bermudezi, observed in the Pleistocene interval of site 132 succession, are rarely recorded in Mediterranean sections. These bioevents however are easily recognized in several oceanic sequences in the same stratigraphic position; consequently, they can be used in the Mediterranean biostratigraphy
Penile Metastases from Renal Cell Carcinoma: Pre and Postcontrast Sonographic Findings
The prostate and bladder are the most common primary cancer sites for penile metastases. Here, we describe an unusual case of metastases from renal cell carcinoma to the penis discovered 1 month after nephrectomy in a 60-year-old man. The diagnosis was achieved using B-mode and contrast-enhanced ultrasound
