Practical consensus recommendations on fertility preservation in patients with breast cancer.

Young women diagnosed with cancer today have a greater chance of long-term survival than ever before. Successful survivorship for this group of patients includes maintaining a high quality of life after a cancer diagnosis and treatment; however, lifesaving treatments such as chemotherapy, radiation, and surgery can impact survivors by impairing reproductive and endocrine health. Expert oncologists along with reproductive medicine specialists discuss fertility preservation options in this chapter since fertility preservation is becoming a priority for young women with breast cancer. This expert group used data from published literature, practical experience and opinion of a large group of academic oncologists to arrive at these practical consensus recommendations for the benefit of community oncologists.

The relationship between vitamin D and chemotherapy-induced toxicity - a pilot study.

BACKGROUND: There are anecdotal data that lower levels of vitamin D may be associated with increased levels of toxicity in individuals receiving chemotherapy; we therefore wished to investigate this further. METHODS: From a cohort of over 11 000 individuals, we included those who had vitamin D levels (serum 1,25(OH)(2)D3) measured before and during chemotherapy. They were analysed for side effects correlating Chemotherapy Toxicity Criteria with vitamin D levels, normalising data for general markers of patient health including C-reactive protein and albumin. RESULTS: A total of 241 (2% of the total cohort) individuals entered the toxicity analysis. We found no overall difference in toxicity effects experienced by patients depending on whether they were vitamin D depleted or had sufficient levels (P=0.78). CONCLUSION: This pilot study suggests routine vitamin D measurement during treatment does not appear to be necessary in the management of chemotherapy-induced toxicity.

Fatal cytomegalovirus pneumonia in patients with haematological malignancies: an autopsy-based case-control study.

Cytomegalovirus (CMV) pneumonia is a life-threatening infection in patients with haematological malignancies (HMs) or in haematopoietic stem cell transplant (HSCT) recipients. To assess the incidence and risk factors for developing fatal CMV pneumonia in these patients, a case-control study based on 999 autopsies was performed at The University of Texas M. D. Anderson Cancer Center, Houston, Texas (January 1990 to December 2004). Twenty-five cases (patients who died with CMV pneumonia) were matched with 34 controls (patients who died without CMV pneumonia) by type of HM or HSCT, year of autopsy, age and gender. The incidence of CMV pneumonia declined between January 1990 to June /1997 and July 1997 to December 2004 (CMV pneumonia rates were 22/620 and 3/379 autopsies, respectively; p 0.006). Logistic regression analysis identified complete remission and sustained lymphopenia as independent predictors of CMV pneumonia (all p <0.05). The incidence of fatal CMV pneumonia has decreased over the last 15 years, which might reflect earlier diagnosis or the use of pre-emptive therapy or more effective preventive strategies. Complete remission of an HM does not preclude the development of CMV pneumonia among patients with prolonged lymphopenia.

Metrondazole-induced neurotoxicity.

A 50 year old male with history of prolonged intake of metronidazole for treatment of liver abscess developed acute ataxia, disorientation, distal symmetrical sensory and proximal motor neuropathy. Patients being treated with metronidazole particularly those on high doses for prolonged period should be monitored for neurotoxicity.

Cat- or dog-induced immediate and late asthmatic responses before and after immunotherapy.

To assess the effect of specific immunotherapy (IT) on the immediate and late asthmatic responses induced by cat or dog extract bronchial provocation testing, we studied seven cat-sensitive and six dog-sensitive subjects with asthma. Among the cat-sensitive subjects, two of three subjects displaying only an immediate asthmatic response before IT lost the response after 3 months of IT with cat extract, whereas only one of four subjects with the dual (immediate and late) asthmatic responses had ablation of such responses (no significance for the one-tailed test). Three subjects had worsening of the immediate response after IT. Among dog-sensitive subjects with asthma, three of five subjects with only an immediate response demonstrated an ablation of the immediate response, whereas the one subject who was the only subject with a dual response before IT lost the dual response after dog-extract IT (p value of 0.005 on one-tailed test). Immediate systemic side effects, including one episode of anaphylaxis, occurred on seven occasions of 326 injections with cat extract compared to only one episode of rhinitis of 289 injections with dog extract.

Clinical spectrum of pulmonary aspergillosis.

Aspergillus produces diverse pulmonary manifestations, its clinical spectrum extending from harmless saprophytic colonization to universally lethal disseminated infection. Management of the conditions produced by Aspergillus is also diverse and may consist of either observation or treatment with corticosteroid agents or amphotericin B. The factors that influence the expression of Aspergillus into a specific clinical entity are not well understood, but are believed to be related to immune status, both pulmonary and systemic, and the genetic composition of the host.
