Sternocleidomastoid muscle metastasis of breast cancer: case report

The authors report a case of 84-year-old women, with dysphagia to liquids and solid foods, and with infiltration of right stemocleidomastoid muscle that compressed the upper third of the esophagus to the thoracic hull. The biopsy of sternocleidomastoid muscle permitted the diagnosis of metastatic breast cancer relapse after 22 years.

Peritoneal tuberculosis associated with adrenocorticol primitive neoplasm mimicking a peritoneal carcinosis: a case report

The authors report a case of women, 51-year-old that presented with peritoneal tuberculosis, with concomitant adrenocortical primitive neoplasm, mistaken as peritoneal carcinomatosis, due to the failure of correct histological analysis. In fact, the critical life status, associated to increases of CA 125, typical imaging of peritoneal carcinomatosis, and presence of 75% atypical cells in ascitic fluid, induced to begin chemotherapy.

Negative impact of bone metastasis on outcome in clear-cell renal cell carcinoma treated with sunitinib

BACKGROUND

The aim of our study was to determine whether the presence of bone metastases affects outcomes in patients with metastatic clear-cell renal cell carcinoma (m-ccRCC) receiving sunitinib.

PATIENTS AND METHODS

We reviewed the charts of all patients in four academic centers in Belgium and France who started first-line sunitinib (50 mg/day; 4 weeks on and 2 weeks off) between January 2005 and December 2008. Data were collected on known prognostic factors for metastatic renal cell carcinoma and metastatic sites. Response and progression were evaluated by computed tomography scan (according to RECIST).

RESULTS

Two hundred twenty-three patients were identified. With a median follow-up of 40 months, median progression-free survival (PFS) and median overall survival (OS) were significantly shorter in patients with bone metastases than in those without: respectively, 8.2 versus 19.1 months (P<0.0001) and 19.5 versus 38.5 months (P<0.0001). On multivariate analysis, taking on account platelet count, Eastern Cooperative Oncology Group performance status, number of metastatic sites, neutrophil count, corrected serum calcium, time from diagnosis to systemic treatment, and the presence of bone metastases, bone metastasis was the independent variable most significantly associated with poor PFS (P<0.0001) and OS (P=0.001).

CONCLUSION

The presence of bone metastases in m-ccRCC patients has a significant and clinically relevant negative impact on outcome on sunitinib.

Bone markers in prostate cancer (PC) patients: Biologic criteria to identify patients at risk of developing distant metastases

e16069

Background: Currently, there are no specific serum and/or urinary bone markers able to accurately identify PC patients with hormone-refractory disease and/or those with distant metastases. Methods: Four categories of PC patients were defined as follows: A. hormone-sensitive without distant metastases; B. hormone-sensitive with metastases; C. hormone-refractory without metastases; D. hormone-refractory with metastases. The serum bone markers investigated were osteogenesis-related [Osteocalcin (OC), procollagen type 1 amino-terminal propeptide (P1NP), bone alkaline phosphatase (BALP)], osteolysis-related [beta collagen 1 carboxyterminal peptide (βCTX), carboxyterminal telopeptide type 1 collagen (1CTP), tartrate resistant acid phosphatase (TRAP)] or osteoclastogenesis-related [osteoprotegerin (OPG)]. Receiver Operating Characteristic (ROC) curves and the Area Under these curves were used to estimate the overall accuracy of each marker in discriminating between the four categories (A vs. BCD; B vs. ACD; C vs. ABD and D vs. ABC) with no adjustment for multiplicity. Parametric (Student's t-test) and non-parametric (Kruskal- Wallis) tests were conducted too. All statistical analyses were performed by means of SPSS v 16 (SPSS Inc). Results: Data were from 40 consecutive PC patients treated at the Georges Pompidou European Hospital in Paris, France and who were equally distributed between categories. Hormone-refractory patients with distant metastases were accurately identified by P1NP, 1CTP and TRAP. The respective areas under the ROC values were 0.76, 0.84 and 0.79 (all Pvalues less than 0.01). None of the markers identified category B of patients. Conclusions: Some bone-related serum markers may be associated with the onset of hormone-refractory status and distant metastases. They should be prospectively validated in a larger cohort of patients.
