ABSTRACT
OBJECTIVE: To establish whether ultrasonographic (US) appearance is correlated to functional outcome in asymptomatic patients 12 months after rotator cuff repair. MATERIAL AND METHODS: 26 asymptomatic patients at twelve months after arthroscopic cuff repair and 26 controls were retrospectively included. A clinical score (Constant's Shoulder Score, CSS) was compared with a US score (the modified Sugaya Score, mSS). The minimal thickness of the anterior and posterior parts of the cuff was also measured. RESULTS: CSS improved significantly from preoperatively to postoperatively (mean increased from 41 to 82.6, p<.001). Correlation between the postoperative CSS and the minimal thickness of the cuff at its anterior and posterior part (p=0.55 and p=0.13) was not significant. There was also no significant correlation between the postoperative CSS and mSS (p=0.34). CONCLUSION: The sonographic appearance of the cuff repair is not correlated to the functional outcome at 12 months after arthroscopic surgery in asymptomatic patients.

PURPOSE: To identify patient/tumor characteristics associated with success of biopsy in patients who received multiple lines of chemotherapy. METHODS: Patients with refractory cancer from our center, who were included in a prospective randomized phase II trial comparing targeted therapies based on molecular profile of tumors versus conventional chemotherapy, were retrospectively included in this IRB-approved study. All patients had a biopsy of a tumor lesion performed during surgery, or using CT/palpation/endoscopic guidance. A biopsy was considered successful if the neoplastic cellularity was greater than 30%. Primary lesion, size and location of biopsied lesion, on-going chemotherapy and the differential attenuation between non-enhanced and venous phase (HU) for CT-guided biopsied lesions were recorded. RESULTS: 228 patients (age=59±15yo; M/F=1.9) were included. One hundred and sixty biopsies (72%) of the 221 biopsies performed were successful. Prognostic factors of biopsy success were: no ongoing chemotherapy, surgical or palpation-guided biopsy, lymph nodes/soft tissue location(P <0.01). Among the 221 performed biopsies, 122 (55%) were performed using CT guidance and 82 (67%) were successful. In this subgroup, biopsied lesions located in lymph nodes/soft tissue were associated with a higher success rate while lung location was associated with failure (P <0.01). The mean differential attenuation was significantly higher in lesions with a successful biopsy (P <0.001). CONCLUSION: Success of biopsy was less frequent with CT guidance than with surgical or palpation-guided biopsy and was higher in soft tissues and lymph nodes than that in visceral metastasis. Ongoing chemotherapy decreased tumor cell content and consequently the success of the biopsy samples for molecular profiling.
