It has previously been reported that a somatostatin analogue has a direct antiproliferative effect on human breast cancer cells in vitro. Here we report preliminary data on the effects of the in vivo administration of SMS in patients with advanced breast cancer. The regimen consisted of iv infusion of 750 micrograms SMS t.i.d. for 10 days followed by 5 days at 500 micrograms im b.i.d. A partial response was observed in 3 out of 10 patients treated. Moreover, a marked reduction of oedema, cyanosis and bleeding from ulcerated tumor lesions was noted in most of the treated patients. Administration of SMS was devoid of toxic side effects. It is suggested that SMS may be of potential value in the therapeutic approach to advanced breast cancer.

It is also common to observe skin manifestations in many internal malignancies. The lung cancer is a frequently seen internal cancer. Due to its gradually increasing incidence, it has become the first reason of death from cancer also in women by overtaking the breast cancer. Although pathognomonic skin manifestations are not reported in lung cancers, it is emphasized that lung cancer must be remembered when non specific signs such as digital clubbing, hypertrophic osteoatropathy, cyanosis due to superior vena cava syndrome, oedema, telengiectasia, acanthosis nigricans are observed. Because a few reports are present about this subject in literature, 44 patients which had the diagnosis of lung cancer in Cumhuriyet University Faculty of Medicine were evaluated according to the their dermatological manifestations. 47.7% of these patients had digital clubbing; meanwhile 25% telengiectasia of the chest forewall, 22.7% lip cyanosis, 9% long eyelash, 2.27% pruritus, 2.27% hypertrophic pulmonary osteoarthropathy and 2.27% Leser Trelat sign were established.

Nine of 24 ovariectomized nude mice developed ulcerative skin lesions 28 d after implantation with human breast cancer cells and slow-release estrogen pellets. Aerobic culture of samples from the skin lesions yielded Staphylococcus intermedius. By day 45 postimplantation, all mice displayed ulcerative skin lesions, and 5 mice exhibited hunched posture, listless behavior, cyanosis, anorexia, and dehydration. This subset was euthanized but not necropsied. When additional animals became moribund, the investigator elected to end the study at day 51. At necropsy, all 20 but 1 had cystitis and urolithiasis, characterized by relatively large struvite stones and crystals that had filled the urinary bladders of the research animals and caused severe thickening of the bladder walls. Gram-positive cocci were observed microscopically in both the kidneys and bladders of the necropsied animals. Spontaneous urolithiasis has not previously been documented to occur in association with infection of female nude mice by S. intermedius.

Spontaneous reporting systems may generate a large volume of information in real world conditions with a relatively low cost. Disproportionality measures are useful to indicate and quantify unexpected safety issues associated with a given drug-event pair (signals of disproportionality), based upon differences compared to the background reporting frequency. This cross-sectional study (2008 to 2013) aimed to analyse the feasibility of detecting such signals in the Brazilian Pharmacovigilance Database comprising suspected adverse drug reactions related to the use of doxorubicin, cyclophosphamide, carboplatin, trastuzumab, docetaxel, and paclitaxel for breast cancer chemotherapy. We first accessed overall database features (patient information and suspected adverse drug reactions) and further conducted a disproportionality analysis based on Reporting Odds Ratios with a confidence interval of 95% in order to identify possible signals of disproportionate reporting, only among serious suspected adverse drug reactions. Of all data reports of adverse reactions (n = 2603), 83% were classified as serious, with the highest prevalence with docetaxel (78.1%). The final analysis was performed using 1,309 reports with 3,139 drug-reaction pairs. The following signals of disproportionate reporting, some rare or not mentioned on labels, were observed: tachypnea with docetaxel; bronchospasm, syncope, cyanosis, and anaphylactic reaction with paclitaxel; and anaphylactic shock with trastuzumab. Structured management of spontaneous adverse drug reaction reporting is essential for monitoring the safe use of drugs and detecting early safety signals. Disproportionality signal analysis represents a viable and applicable strategy for oncology signal screening in the Brazilian Pharmacovigilance Database.
