  9. Testicular Cancer - Treatment Overview for Acute Myeloid Leukemia (AML)

    There is presently no therapeutically or prognostically meaningful staging system for these disorders. Leukemia is considered to be disseminated in the hematopoietic system at diagnosis, even in children with acute myeloid leukemia (AML) who present with isolated chloromas (also called granulocytic sarcomas). If these children do not receive systemic chemotherapy, they invariably develop AML in months or years. AML may invade nonhematopoietic tissue such as meninges, brain parenchyma, testes or ovaries, or skin (leukemia cutis). Extramedullary leukemia is more common in infants than in older children with AML.[1]Newly DiagnosedChildhood AML is diagnosed when bone marrow has greater than 20% blasts. The blasts have the morphologic and histochemical characteristics of one of the French-American-British subtypes of AML. It can also be diagnosed by biopsy of a chloroma. For treatment purposes, children with a t(8;21) and less than 20% marrow blasts should be considered to have AML rather

  10. Bladder Cancer Treatment (PDQ®): Treatment - Health Professional Information [NCI] - Distal Urethral Cancer

    Female Distal Urethral CancerIf the malignancy is at or just within the meatus and superficial parameters (stage 0/Tis, Ta), open excision or electroresection and fulguration may be possible. Tumor destruction using Nd:YAG or CO2 laser vaporization-coagulation represents an alternative option. For large lesions and more invasive lesions (stage A and stage B, T1 and T2, respectively), brachytherapy or a combination of brachytherapy and external-beam radiation therapy are alternatives to surgical resection of the distal third of the urethra. Patients with T3 distal urethral lesions, or lesions that recur after treatment with local excision or radiation therapy, require anterior exenteration and urinary diversion. If inguinal nodes are palpable, frozen section confirmation of tumor should be obtained. If positive for malignancy, ipsilateral node dissection is indicated. If no inguinal adenopathy exists, node dissection is not generally performed, and the nodes are followed clinically.
