ReviewRationale and techniques of intra-operative hyperthermic intraperitoneal chemotherapy.
In recent years surgical cytoreduction followed by intra-operative hyperthermic intraperitoneal chemotherapy (HIPEC) was introduced as treatment modality in patients with peritoneal surface malignancy. In the current review the rational for this approach, the prerequisites and the different techniques used are discussed. ⋯ Aggressive surgical cytoreduction and HIPEC in patients with peritoneal surface malignancy has a clear rational and seems to have clinical value.

ReviewNew options for outpatient chemotherapy--the role of oral fluoropyrimidines.
For several decades fluoropyrimidines, especially 5-fluorouracil (5-FU), have played a role in standard chemotherapy regimens for a range of solid tumours, including breast and colorectal cancers. In recent years, schedule modification and biomodulation have achieved improved efficacy and tolerability. However, the complications arising from infused intravenous administration are well-recognized and there is an unmet medical need for oral agents with improved efficacy and tolerability, offering more convenient outpatient therapy. ⋯ Capecitabine is also effective in patients with taxoid-pretreated metastatic breast cancer, a population which previously had no established treatment options. Both capecitabine and UFT/leucovorin are being evaluated in combination with irinotecan and oxaliplatin in colorectal cancer, and vinorelbine and docetaxel/paclitaxel in breast cancer. In the future, these more convenient, oral fluoropyrimidines may replace intravenous 5-FU in the treatment of breast and colorectal cancer.

ReviewPostoperative irradiation in endometrial cancer: still a matter of controversy.
Although endometrial cancer is the most common female malignancy, evidence-based uniform guidelines for postoperative therapy have not been established. The most logical management is adjuvant irradiation tailored to the extent of surgery, the tumour grade, depth of myometrial invasion, degree of lymph node involvement and age of the patient. Currently, the only widely accepted treatment recommendations are no further therapy in low-risk patients who underwent extensive surgical staging, and external beam radiotherapy (EBRT) in high-risk patients. ⋯ The role of adjuvant radiotherapy (EBRT with or without BRT) in high-risk patients as well as the value of lymphadenectomy in patients fit for such surgery is being addressed in a trial co-ordinated by the Medical Research Council. Future studies are warranted to define whether any irradiation should be employed in intermediate-risk patients and which radiotherapy modality should be used in high-risk node-negative patients with stage I tumours (stage Ib grade 3 and all stage Ic). Other issues which should be addressed in future studies include the extent of surgery, the role of systemic therapies, the relevance of novel biologic prognostic factors, salvage therapies after recurrence, cost-benefit analysis and quality of life.

Paget's disease of the breast is a rare disorder of the nipple-areola complex that is often associated with an underlying in situ or invasive carcinoma. A change in sensation of the nipple-areola, such as itching and burning, is a common presenting symptom. Objectively, eczematoid changes of the nipple-areola complex are common. ⋯ Nowadays, however, some patients with Paget's disease of the breast are candidates for breast-conserving therapy. Patients must be selected carefully on an individual basis. Until there is a better understanding of the relationship of Paget's disease of the breast to the underlying cancer the surgeon should understand the natural history and behaviour of this lesion and be aware of both the risks of under- and over-treating patients with Paget's disease of the breast.

ReviewDuctal carcinoma in situ (DCIS) of the breast: evolving perspectives.
Ductal carcinoma in situ (DCIS) of the breast is an early, localized stage of carcinoma in the process of multistep breast carcinogenesis. The incidence of DCIS is increasing, mainly due to screening mammography, which results in diagnosing the disease in an increasing proportion of asymptomatic patients. Consequently, clinicians are being confronted with growing numbers of women who present with DCIS of the breast; thus, the concepts of managing such patients are assuming greater importance. ⋯ The role of tamoxifen in the treatment of DCIS is not clearly defined; tamoxifen should be given only in patients enrolled in clinical trials. Following breast-conservation therapy, about 50% of the tumours recur as invasive cancer. Most patients with recurrent disease can be treated effectively, usually by salvage mastectomy, but also in selected cases by breast-conservation therapy.
