Breast Tuberculosis after Chest Trauma - a Case Report and Review of the Literature.

BACKGROUND: Breast involvement of tuberculosis (TB) is well known but uncommon. It can resemble other diseases, including breast cancer, and diagnosis is quite difficult. So, when facing a breast lesion, a possible tubercular etiology should always be born in mind, relying on qualified laboratories to confirm the diagnosis. CASE REPORT: We describe a 42-year-old woman with a mammary fistula complicating a post-traumatic lump. A critical analysis of the diagnostic process was performed together with a review of the literature, also considering the potential role of trauma in inducing such a rare complication.

Limited usefulness of QuantiFERON-TB Gold In-Tube for monitoring anti-tuberculosis therapy.

The usefulness of IFN-gamma release assays to monitor the efficacy of anti-tuberculosis (TB) treatment is controversial. Sixty patients affected by culture-confirmed pulmonary TB (M = 36; mean age: 39.2 yr; Italians = 28) were serially tested in a low prevalence setting by means of QuantiFERON-TB GOLD In-Tube (QFT-IT) at baseline and after a successful six-month therapy regimen (T6). A sub-group of 40 cases was also tested at 1 and 3 months. Overall, 88.3% of patients scored a QFT-IT positive result at baseline, with the higher proportion of TB-specific IFN-gamma responses in foreign-born patients (p = 0.04). TB-specific responses were highly variable over time, the within-person variability being correlated with baseline IFN-gamma levels (r = 0.731; p < 0.001). Overall, 61.6% of cases still tested QFT-IT positive at the completion of therapy. Average IFN-gamma levels increased over time, being persistently significantly higher in Italian patients than in foreign-born cases both at baseline (p = 0.03) and at T6 (p = 0.02). Reversion mainly occurred in patients (26.6%) with baseline IFN-gamma levels close to the conventional cut-off value. No indeterminate results were recorded at any study time point. In conclusion, QFT-IT adds no significant information to clinicians for treatment monitoring when applied in routine clinical practice in a low prevalence setting. Kinetics of T cell responses upon TB treatment and reversion (and conversion) thresholds need to be addressed. Diversity of IFN-gamma responses among patients of different geographic origin is an issue to be investigated further.

Platinum-etoposide chemotherapy in elderly patients with small-cell lung cancer: results of a randomized multicenter phase II study assessing attenuated-dose or full-dose with lenograstim prophylaxis--a Forza Operativa Nazionale Italiana Carcinoma Polmonare and Gruppo Studio Tumori Polmonari Veneto (FONICAP-GSTPV) study.

PURPOSE: Small-cell lung cancer (SCLC) is increasingly diagnosed in elderly patients, who are at higher risk of treatment-related morbidity and mortality. We conducted a randomized two-stage phase II study to assess the therapeutic index of two different platinum/etoposide regimens, attenuated-dose (AD) and full-dose (FD) plus prophylactic lenograstim. PATIENTS AND METHODS: SCLC patients older than 70 years were randomized to receive four courses of cisplatin 25 mg/m(2) on days 1 and 2, and etoposide 60 mg/m(2) on days 1, 2, and 3 every 3 weeks (AD); or cisplatin 40 mg/m(2) on days 1 and 2, and etoposide 100 mg/m(2) on days 1, 2, and 3 every 3 weeks, plus lenograstim 5 mg/kg days 5 through 12, every 3 weeks (FD). A combined primary end point named therapeutic success (TS), which took into account activity, toxicity, and compliance, was used. RESULTS: Ninety-five patients were enrolled. Seventy-five percent and 72% of the patients in the AD and FD arms, respectively, completed the treatment as per protocol. Response rate was 39% and 69% in the AD and FD arms, respectively, and 1-year survival probability was 18% and 39%, respectively. Treatment was well tolerated in both groups, with no grade 3 to 4 myelotoxicity in the AD arm, and 12% myelotoxicity in the FD arm. Overall, the observed TSs were 10 (36%) of 28 patients and 42 (63%) of 67 patients for AD and FD treatments, respectively. CONCLUSION: In elderly patients with SCLC a full-dose cisplatin/etoposide regimen combined with prophylactic lenograstim is active and feasible, while attenuated doses of the same regimen are associated with a poor therapeutic outcome.
