Because treatment with surgery and combination chemotherapy produces a high cure rate in young men with osteosarcoma, their subsequent reproductive function is an important concern. Semen analyses of osteosarcoma patients, therefore, were performed before, during, and after treatment with the PADIC regimen consisting of cisplatin, Adriamycin (doxorubicin), and dacarbazine or, in some cases, the PADIC regimen plus additional drugs. Results showed that semen volume was not affected and that sperm motility was reduced only during treatment. Although nearly all patients were rendered azoospermic during treatment, sperm production resumed in 30 of 32 patients examined at least 2 years after treatment. Analysis with correction for censored data indicates that, in 78% of treated men, sperm counts will return to more than 10 million/ml. The percentage of men whose sperm counts recovered to normal was lower for those receiving cisplatin dosages greater than or equal to 600 mg/m2; no trends were observed with Adriamycin and dacarbazine dosages. The inclusion of additional drugs such as methotrexate, bleomycin, dactinomycin, or cyclophosphamide (less than 4 g/m2) did not significantly affect the recovery of spermatogenesis. We conclude that the risk of long-term infertility from treatment with the PADIC regimen is low.

Four women were referred to the department ofGynaecology for fertility preservation. A 33-year-old nulliparous woman with breast cancer stage pT1cN0M0 underwent an IVF-ICSI cycle; five embryos were frozen. Pre-implantation genetic diagnosis (PGD) because of BRCA2 gene mutation carriage was not carried out and more recently follow-up oocyte donation options are being considered. A second, 32-year-old nulliparous woman with breast cancer stage pT2N1M0 underwent an IVF cycle; seven embryos were frozen. The third patient was a 14-year-old girl with osteosarcoma of the distal femur, who underwent a laparoscopic unilateral ovariectomy, one day after referral, and cortical tissue was frozen. The fourth patient was a 33-year-old nulliparous woman without partner, with non-Hodgkin lymphoma stage IIA. She underwent laparoscopic ovariectomy and cortical tissue was frozen. Infertility due to cancer treatment and fertility preservation options should be discussed early in treatment planning. Patients' expectations and fertility preservation limitations are important to consider. Fertility preservation options can be conducted in specialised hospitals under institutional review board approval. It still has an experimental status.

Since the introduction of multi-agent chemotherapy for osteosarcoma over 30 years ago, overall survival has exceeded 50%. A clear understanding of the acute complications and late effects of osteosarcoma therapy is required to care effectively for patients with osteosarcoma undergoing active treatment, and for the increasing number of osteosarcoma survivors. There has now been sufficient cumulative experience treating patients with osteosarcoma with active anti-osteosarcoma chemotherapy agents, high-dose methotrexate, doxorubicin, cisplatin, ifosfamide, and etoposide to recognise and understand rare toxicities associated with these agents, and to identify the late effects of osteosarcoma therapy. Late effects and rare toxicities of osteosarcoma include cardiac toxicity, acute and chronic nephrotoxicity, neurotoxicity, hearing loss, infertility, and second malignant neoplasms. Reducing the complications of osteosarcoma therapy is an important goal that will require the identification of clear prognostic indicators, the development of biologically-based therapies, and improved antidotes for the active anti-osteosarcoma cytotoxic drugs.

The combination of cisplatin, doxorubicin, and methotrexate was established as the standard backbone of contemporary osteosarcoma therapy in 1986. Since then, however, further improving the survival of patients with osteosarcoma has been challenging-30% to 40% of patients with osteosarcoma still die of this disease. In addition, these patients often experience loss of fertility at a young age, short- and long-term treatment-related cardiotoxicity, and adverse orthopedic effects from surgical resection of the tumor or endoprosthetic reconstructions. Cancer treatment often markedly increases the risk of infertility later in life, causing many patients substantial distress and regret. Sperm banking and oocyte cryopreservation are standard of care and should be available to all at-risk patients. Newer techniques, such as autologous gonadal tissue transplant for prepubertal children, are being developed, and newer systemic agents have infertility risk profiles that remain undefined and warrant further study. Cost and access remain barriers to these options. The late effects of anthracycline-induced cardiotoxicity are also increasingly a problem for these patients. These effects are often progressive and can be disabling. Adding dexrazoxane to doxorubicin therapy significantly reduces the risk for most adverse cardiac outcomes without compromising the efficacy of induction chemotherapy. Limb salvage surgery remains the standard of care for treatment in the majority of patients with extremity sarcomas. Modular metal prostheses and allograft reconstructions comprised the majority of surgical procedures for limb salvage surgery. The most common mechanism of failure of these implants is infection and mechanical failure of the implant.
