| Popis: | 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. |
