Palliative care in patients with ovarian cancer and bowel obstruction.

OBJECTIVE: Malignant bowel obstruction (MBO) is usually a pre-terminal event in patients with ovarian cancer. However, because of the lack of data in literature, decisions around surgical intervention, non-resectional procedures, or medical treatment of MBO in patients with ovarian cancer cannot be lightly undertaken. We analyzed medical and surgical procedures, performance status, nutritional status, cachexia, and their prognostic value in this group of patients. METHODS: We retrospectively selected all consecutive patients with recurrent ovarian cancer who received medical or surgical treatment for MBO between October 2008 and January 2014 at the Academic Department of Gynecological Oncology of Mauriziano Hospital of Turin (Italy). RESULTS: We found 40 patients: 18 of them underwent medical treatment and 22 of them were submitted to surgery. In the group of surgery, the hospitalization was shorter (p 0.02), the pain reduction was more effective (p 0.001), the number of chemotherapy lines was higher (p 0.03), and re-obstruction was more rare (p 0.02). Between the two groups, we did not find any differences in post-palliation episodes of vomit (p 0.83), type of diet (p 0.34), ability to return home (p 0.72), and death setting (p 0.28). Median survival after palliation was longer in the group of surgery (p 0.025). Cachexia, low performance status, and poor nutritional status were significant predictors of worse survival after MBO, independently by the treatment. CONCLUSIONS: Surgery has to be considered in patients without serious contraindications; otherwise, a medical protocol, including antisecretory drugs, is the standard of care in frail patients.

Unilateral phrenic nerve paralysis: a rare complication after total thyroidectomy for a large cervico-mediastinal goitre.

Unilateral phrenic nerve paralysis is a rare complication of cervico-mediastinal goitre. It occurs when adhesions grow between the intrathoracic part of the thyroid and the nerve, specially where the goitre enters the mediastinum behind the first rib. The damage may be caused by strain of the nerve due to the descent of the goitre into the chest or may be caused by the surgical manoeuvres during thyroidectomy performed by cervical approach. Two patients operated on for large cervico-mediastinal goitre are reported: a 70-year-old male with a large intrathoracic growth of the left thyroid lobe and a 54-year-old male with a large intrathoracic growth to the right lobe. A few days after total thyroidectomy they showed signs of exertional dyspnoea. The exams performed showed hemi-diaphragm relaxatio due to phrenic nerve paralysis, with resulting reduction of respiratory space. Phrenic nerve paralysis may follow total thyroidectomy for large cervico-mediastinal goitres; is not due to the operative technique, but rather to the particular anatomic conditions which may be found.

Thyroid cancer histotype changes as observed in a major general hospital in a 21-year period.

The existing registries of thyroid carcinoma are seldom comparable as far as epidemiological data, diagnostic criteria and histopatological description are concerned. Epidemiological studies report a progressive increase in the incidence of thyroid carcinoma in the last twenty years and in both sexes this increase of incidence has been referred to papillary histotype. Data collected from surgical series show a rate of thyroid carcinomas from 7 to 20% of total thyroid surgeries. The present study was designed in order to obtain a retrospective review of the distribution of thyroid carcinoma's different histotypes in the last 21 years in a major General Hospital. Detailed analysis of patients with histologically confirmed thyroid carcinoma admitted between 1974 and 1994 to the Surgery Department of Mauriziano Hospital of Torino, Italy showed an overall 11.8% prevalence of thyroid cancer out of the total thyroid surgeries. The rate of papillary carcinoma was the highest (54.3%) followed by follicular carcinoma (27.6%), anaplastic carcinoma (11.1%), medullary carcinoma (4.6%) and others (2.4%). The papillary-to-follicular ratio varied from 0.60 in 1974-76 to 6.88 in 1992-94. Female to male ratio of all thyroid carcinoma histotypes was 2.0 or more; papillary and follicular histotypes had the highest ratio. The variations of the histotype rate observed may be consequence of the silent increase of daily iodine intake throughout the subsequent years, while improved diagnostic tools available and increased experience of the medical staff have probably increased the number on thyroid ablations performed. Our data confirm the changing epidemiology of thyroid carcinoma, reported by international literature.
