A 66-year-old female presented with a swollen lump in the left breast. She was diagnosed as having advanced breast cancer of stage T4N3 (supraclavicular lymph node) M1 (bone). The administration of CEF and TAM failed to improve her condition. After the treatment regimen was changed to combined chemoendocrine therapy with CPA, EPI, 5'-DFUR, and MPA, the areas of bone metastases were reduced. However, MPA caused side-effects (acute obstruction of the lower limb), and thus the treatment was discontinued after 4 months. Subsequently, the treatment combination was changed to CPA, EPI, 5'-DFUR, and fadrozole hydrochloride hydrate. After one year of the treatment, a complete response (CR) was obtained with the disappearance of the supraclavicular lymph node and bone metastases. After EPI reached the maximum administration amount, the remaining CPA, 5'-DFUR and fadrozole hydrochloride hydrate oral administrations were continued. As of 3 years and 10 months after the onset of the chemoendocrine therapy, CR has been maintained with suppression of the primary and metastatic lesions, without degrading the patient's quality of life.

Case 1: A 34-year-old woman,who had a right breast cancer with axillary lymph node metastasis and multiple bone metastases, was referred to our clinic. She developed paralysis of lower extremities and disorder of the bladder and rectum due to metastasis to the thoracic vertebra, and also had renal dysfunction due to severe hypercalcemia and hemorrhagic cystitis. Correcting the serum calcium level with intravenous infusion, elcatonin, pamidronate and betamethasone, she underwent radiation therapy for the vertebral metastasis. The first hormonal therapy (leuprorelin/exemestane) had been effective for about 4 months, however the second hormonal therapy (leuprorelin/tamoxifen) was not effective. Chemotherapy with paclitaxel (80 mg/m(2), day 1, 8, 15, every 4 weeks) brought about a stable general condition and a normal level of serum calcium with zoledronate in the ninth month of treatment. Case 2: A 32-year-old woman, who had a right breast cancer with multiple bone metastases and axillary and hilar lymph node metastases, came to our clinic, complaining of nausea due to severe hypercalcemia. After successful correction of hypercalcemia by the intravenous infusion and administration of elcatonin, pamidronate and dexamethasone, the hormonal therapy(goserelin/tamoxifen) caused rapid re-elevation of serum calcium and tumor marker, so that a tumor flare was suspected. After 3 cycles of EC therapy (EPI 90 mg/m(2), CPM 600 mg/m(2), every 3 weeks), 2 cycles of paclitaxel therapy (80 mg/m(2), day 1, 8, 15, every 4 weeks) brought about tumor reduction and the normal level of serum calcium. After 7 cycles of paclitaxel therapy,the hormonal therapy (goserelin/tamoxifen) proved effective for several months. To achieve tumor reduction and stabilize the serum calcium level, we need to start immediately the treatment of breast cancer with severe hypercalcemia, considering the general condition of the patient.

The therapeutic landscape of metastatic castration-resistant prostate cancer (mCRPC) has been revolutionized by the arrival of multiple novel agents in the past 2 years. Immunotherapy in the form of sipuleucel-T, androgen axis inhibitors, including abiraterone acetate and enzalutamide, a chemotherapeutic agent, cabazitaxel, and a radiopharmaceutical, radium-223, have all yielded incremental extensions of survival and have been recently approved. A number of other agents appear promising in early studies, suggesting that the armamentarium against castrate-resistant prostate cancer is likely to continue to expand. Emerging androgen pathway inhibitors include androgen synthesis inhibitors (TAK700), androgen receptor inhibitors (ARN-509, ODM-201), AR DNA binding domain inhibitors (EPI-001), selective AR downregulators or SARDs (AZD-3514), and agents that inhibit both androgen synthesis and receptor binding (TOK-001/galeterone). Promising immunotherapeutic agents include poxvirus vaccines and CTLA-4 inhibitor (ipilimumab). Biologic agents targeting the molecular drivers of disease are also being investigated as single agents, including cabozantinib (Met and VEGFR2 inhibitor) and tasquinimod (angiogenesis and immune modulatory agent). Despite the disappointing results seen from studies evaluating docetaxel in combination with other agents, including GVAX, anti-angiogentic agents (bevacizumab, aflibercept, lenalinomide), a SRC kinase inhibitor (dasatinib), endothelin receptor antagonists (atrasentan, zibotentan), and high-dose calcitriol (DN-101), the results from the trial evaluating docetaxel in combination with the clusterin antagonist, custirsen, are eagerly awaited. New therapeutic hurdles consist of discovering new targets, understanding resistance mechanisms, the optimal sequencing and combinations of available agents, as well as biomarkers predictive for benefit. Novel agents targeting bone metastases are being developed following the success of zoledronic acid and denosumab. Finally, all of these modalities do not appear curative, suggesting that clinical trial enrollment and a better understanding of biology remain of paramount importance.
