8We Are YoungA nulliparous 29-year-old Ashkenazi Jewish woman has a palpable left breast mass present for 6 months. Her mother was adopted; her father is 72 years old and has a history of prostate cancer. Her paternal aunt was diagnosed with ovarian cancer at age 48 years. Another paternal aunt was diagnosed with breast cancer at age 49 years. Her paternal grandmother died of complications from breast cancer at age 60 years. On exam, there is a 4-cm mass in the left breast affixed to the chest wall and a 1-cm, freely movable left axillary lymph node. Biopsy reveals moderately differentiated ER+, PR+, H2N- invasive ductal carcinoma. CT and bone scan show no metastatic disease. She will receive preoperative chemotherapy followed by surgery. Which of the following will be most helpful in determining the best surgical approach? A. Counseling and genetic testing B. Genomic profile assay C. PET scan D. Tumor marker testing
9Key PointFor women who have breast cancer and are at high risk for BRCA1 or BRCA2 mutations, genetic testing and counseling may inform surgical options.
10BRCA1 and BRCA2 risk2 1st degree relatives with breast cancer (one at <50 years of age)2 or more 1st or 2nd degree relatives with ovarian cancer regardless of age;3 or more 1st or 2nd degree relatives with breast cancer regardless of age;1st or 2nd degree relative with both breast and ovarian cancer at any age; orBoth breast and ovarian cancer among 1st and 2nd degree relatives;Breast cancer in a male relative.1st degree relative with bilateral breast cancer;
11Why genetic testing? The history suggests genetic cancer Test results either:Establish the diagnosisInfluence the management of family members at riskTest those already with cancer if at all possible
12I Can’t Go For ThatA 65-year-old woman is evaluated for a 2-cm right breast mass discovered on routine mammography. Vital signs and physical exam are unremarkable, and there is no palpable breast mass or lymphadenopathy. Ultrasound-guided needle biopsy reveals a well-differentiated, ER+, PR+, H2N- invasive ductal carcinoma. Which of the following is the most appropriate next step in management? A. Right breast lumpectomy B. Right breast lumpectomy, sentinel lymph node biopsy, and radiation C. Right breast mastectomy D. Right breast mastectomy, sentinel lymph node biopsy, and radiation
13Key PointBreast conservation therapy, which consists of excision of the primary tumor and radiation therapy, is equivalent to mastectomy in long-term survival.
14Primary therapy All breast cancer patients need surgery at some point. Breast-conserving therapy is equivalent to mastectomy.Sentinel lymph node biopsy:For clinically lymph node negative diseaseFewer side effects (far less lymphedema)Adjuvant radiation reduces local recurrence.

FluoxetineB. Low-dose estrogen-progesteroneC. Red cloverD. Venlafaxine
28Key PointSelective serotonin reuptake inhibitors that are potent CYP2D6 inhibitors (such as fluoxetine and paroxetine) should be avoided in patients with menopausal symptoms caused by tamoxifen.
2950 Ways to Say GoodbyeA 65-year-old woman is evaluated during a routine examination. She is asymptomatic. She had stage I ER-, PR-, HER2- breast cancer diagnosed 3 years ago treated with modified radical mastectomy followed by chemotherapy with docetaxel and cyclophosphamide. On physical exam, the left chest wall is well healed with no nodularity. No right breast masses, axillary lymphadenopathy, or supraclavicular lymphadenopathy are present. The patient will undergo periodic mammography and routine health maintenance. Which of the following would be the most appropriate additional evaluation in this patient? A. Bone scan yearly B. CT scan yearly C. PET scan yearly D. Tumor marker measurement, complete blood count, and comprehensive metabolic panel yearly E. No additional studies
30Key PointThe use of screening blood tests (including tumor markers) and imaging is not recommended for routine breast cancer follow-up in an otherwise asymptomatic patient with no specific findings on clinical examination.

89Head GamesA 46-year-old woman is evaluated for the recent onset of headaches that are most intense on waking in the morning and are not relieved by analgesics. She has no nausea or vomiting but notes some difficulty with fine motor skills when using her right hand. The patient has a 2-year history of stage II breast cancer last treated with chemotherapy 2 years ago.Funduscopic exam reveals papilledema. She has reduced strength (4/5+) in her right hand.A CT of the head reveals 2 separate masses in the left temporal lobe with associated edema, as well as blastic lesions involving the skull.Which of the following is the most appropriate management?A. ChemotherapyB. Intravenous dexamethasone and radiation therapyC. Lumbar punctureD. Resection of the masses
90Key PointImmediate corticosteroid administration and early initiation of radiation therapy are indicated to treat brain metastasis and increased intracranial pressure.
92Risk and ScreeningThe most significant risk factor for ovarian cancer, especially in premenopausal women, is the presence of BRCA1/BRCA2 gene mutations; hereditary nonpolyposis colorectal cancer syndrome also confers a significantly increased risk.Use of oral contraceptive agents decreases the risk of ovarian cancer by as much as 50% with the protective effect lasting up to 20 years after oral contraception cessation.Screening for ovarian cancer is not recommended for average-risk women.In women at high risk for developing ovarian cancer, prophylactic bilateral salpingo-oophorectomy before age 40 years reduces the risk of developing cancer by 95%.
93Diagnosis and StagingMost patients with ovarian cancer have advanced disease at initial evaluation.Findings on ultrasonography suggestive of ovarian cancer include a solid mass, a cyst with thick septations, and ascites.The diagnosis of advanced ovarian cancer is usually made by CT or ultrasound-guided biopsy of a suspicious mass or cytologic examination of ascitic fluid.
94Surgical RoleOptimal tumor debulking (no residual tumor mass >1 cm) is associated with increased survival in patients with ovarian cancer.Surgical resection is appropriate for patients with a recurrent solitary ovarian tumor or with limited relapse of cancer at sites favorable for surgical removal.
95ChemotherapyAdjuvant chemotherapy is indicated for patients with high-risk, early-stage ovarian cancer and those with advanced disease.Use of hematopoietic growth factors to maintain adequate blood counts has helped improve the quality of life and decrease complication rates in patients with ovarian cancer who are receiving chemotherapy.
96Follow-upPatients who have completed initial treatment for ovarian cancer require routine follow-up clinical evaluations, including history, physical examination, and serum CA-125 measurement.
98Pancreatic CancerPatients with metastatic pancreatic cancer have a median survival ranging from 4 to 6 months; those with locally unresectable disease have a median survival of about 1 year.Surgery is the only potentially curative intervention for patients with pancreatic cancer who have an apparent technically resectable tumor without evidence of metastases.
99Gastric CancerHelicobacter pylori infection is a major risk factor for development of gastric cancer.In patients who undergo surgery as initial therapy for gastric cancer, postoperative 5-fluorouracil and leucovorin plus radiation therapy have been shown to confer a survival benefit compared with postoperative observation alone.Patients with gastric and gastroesophageal junction adenocarcinoma whose tumors expressed HER2 experienced statistically significantly improved median survival when trastuzumab was added to cisplatin plus 5-fluorouracil or capecitabine.
100Esophageal CancerGastroesophageal reflux disease, Barrett esophagus, and obesity are risk factors for esophageal cancer.The diagnosis of esophageal cancer is established by upper endoscopy and biopsy.Local and locoregional esophageal cancers are usually treated surgically; perioperative treatment with chemotherapy or chemotherapy plus radiation therapy may improve survival.
101Anal CancerAnal cancer is treated initially with combined radiation therapy and chemotherapy.Mitomycin plus 5-fluorouracil is the standard chemotherapy regimen used in conjunction with radiation therapy in the treatment of anal cancer.
103StructuralSuperior vena cava syndrome is most often caused by lung cancer; other causes are lymphoblastic and diffuse large B-cell lymphoma, Hodgkin lymphoma, and germ cell tumors.Primary therapy for the underlying malignancy is usually associated with rapid and complete resolution of symptoms and physical findings of superior vena cava syndrome.Lumbar puncture is contraindicated when increased intracranial pressure is due to mass effect because the procedure may precipitate catastrophic brainstem herniation.
104StructuralCorticosteroids such as dexamethasone are initially used to treat patients with increased intracranial pressure.Patients with breast, lung, and prostate cancer are most likely to develop spinal cord compression.Patients with suspected spinal cord compression require prompt diagnosis (MRI of the spine), usually before any motor deficit is detected, and immediate administration of corticosteroids.
105StructuralA malignant pleural effusion is most often caused by lung cancer, breast cancer, and lymphoma, and less frequently by cancer of unknown primary site.Thoracentesis is required for immediate palliation of a symptomatic malignant pleural effusion.Excessive drainage in patients with malignant pleural effusion should be avoided to prevent pulmonary edema following lung re-expansion.Echocardiography is essential to establish the diagnosis of malignant pericardial effusion.
106MetabolicPrevention and treatment of tumor lysis syndrome require hydration with normal saline as well as allopurinol or rasburicase in high-risk patients to limit the degree of hyperuricemia.Symptoms of hypercalcemia include nausea and vomiting, constipation, polyuria and polydipsia, weakness, and confusion.The mainstays of treatment of hypercalcemia are aggressive hydration with normal saline for short-term control and parenteral bisphosphonates for longer-term control.
108ChemotherapyThe risk of life-threatening infection in patients receiving cancer treatment significantly increases with absolute neutrophil counts lower than 500/µL (0.5 × 109/L) and as the duration of neutropenia increases.Recombinant granulocyte colony-stimulating factor and granulocyte-macrophage colony-stimulating factor are effective in preventing neutropenia and neutropenic fever and maintaining the dose intensity of chemotherapy.Myelodysplasia and leukemia can be caused by chemotherapy and, to a lesser extent, radiation therapy.
109OtherInvolved-field radiation therapy may cause acute and chronic cardiac disorders.Patients with breast cancer who are treated with combined chemotherapy or radiation have an increased lifetime risk for developing myelodysplasia, leukemia, endometrial cancer, and rarely, soft tissue sarcoma.Long-term administration of aromatase inhibitors in women with breast cancer has significantly increased the incidence of osteopenia and risk for late pathologic fractures.
111Risk and PresentationThe major risk factors for development of head and neck cancer are alcohol and tobacco use.Epstein-Barr virus and human papillomavirus infection may be responsible for development of head and neck cancer in a subset of patients without a history of tobacco use.
112Diagnosis and StagingPresenting signs and symptoms of head and neck cancer depend on the location of the primary tumor.Patients with cervical lymphadenopathy require expert evaluation of the upper aerodigestive tract to identify a primary lesion; fine-needle aspiration of a palpable lymph node is performed, followed by a lymph node biopsy if the aspirate is nondiagnostic.
113TreatmentGoals of treatment of head and neck cancer focus on improving survival while preserving organ function and minimizing complications.Early-stage (stage I and II) head and neck cancer is highly curable with surgical resection or radiation therapy.Locally advanced stage III and IV head and neck cancer is treated with a combination of surgical resection, radiation therapy, and chemotherapy.Complications following treatment of head and neck cancer include damage to cranial and sensory nerves, xerostomia, swallowing dysfunction, voice changes, altered taste sensation, fibrosis, dental problems, and esophageal strictures.
115Germ Cell TumorTesticular cancer is the most common solid tumor in young men and is one of the most highly curable of all malignancies.The primary risk factors for development of testicular cancer are the presence of Klinefelter syndrome, cryptorchidism, and a family history of testicular cancer.Patients with testicular cancer usually present with a unilateral mass or testicular swelling.
116Germ Cell TumorInitial urologic evaluation of a patient with suspected testicular cancer includes a chest radiograph, CT scan of the abdomen and pelvis, and determination of serum tumor marker levels.All patients with testicular cancer (either seminoma or nonseminoma) require radical orchiectomy as initial treatment.Patients with nonseminoma have a poorer prognosis than those with seminoma and require more aggressive treatment, but even with widespread metastases, may be cured with additional surgery and combination chemotherapy.
117Bladder CancerMost bladder cancers occur in men, who are typically over 60 years of age.Cigarette smoking is the major risk factor for development of bladder cancer.Patients with bladder cancer most often present with painless hematuria.All components of the urinary tract must be evaluated in patients with hematuria to identify a potential malignant source (or sources) of bleeding.
118Bladder CancerApproximately 60% of patients with bladder cancer are found to have noninvasive disease at the time of initial TNM staging.Patients with noninvasive bladder cancer are usually treated with transurethral resection of the bladder tumor and have an excellent prognosis.Patients with bladder cancer that invades muscle usually require radical cystectomy, including removal of the bladder, adjacent pelvic organs, and regional lymph nodes.Metastatic bladder cancer is incurable, and palliative platinum-based chemotherapy is often used in this setting.
119Renal Cell CancerMost patients with renal cell cancer present with a mass found incidentally on a radiographic study performed for other reasons.Large solid tumors seen on ultrasound imaging are so likely to be renal cell carcinoma that needle biopsy is not needed before definitive surgical resection is planned.Partial nephrectomy is appropriate for patients with renal cell tumors measuring less than 4 cm that are not adjacent to the renal pelvis.Molecularly targeted agents such as sunitinib, sorafenib, bevacizumab, temsirolimus, and everolimus have been shown to be effective in treating patients with resected renal cell cancer who develop metastatic disease.
121DiagnosisBefore more specialized studies are done in patients with cancer of unknown primary site, biopsy samples of tumor from the most accessible location should be obtained for immunohistochemical marker determinations.An exhaustive search for a primary tumor should not be done in patients with cancer of unknown primary site because finding an asymptomatic and occult primary tumor has not been shown to improve outcome.Evaluation of patients with cancer of unknown primary (CUP) site should focus on whether findings are consistent with a treatable primary tumor or a treatable subtype of CUP.
122Treatment & PrognosisWomen with cancer of unknown primary site associated with isolated malignant axillary lymphadenopathy should be assumed to have locoregional breast cancer until proved otherwise.Women with cancer of unknown primary site presenting as abdominal carcinomatosis and ascites should be assumed to have ovarian cancer until proved otherwise.Patients with cancer of unknown primary site that is not included in a favorable subgroup generally have a poor prognosis and typically receive empiric therapy.
124Risk & TreatmentRisk factors for melanoma include sun exposure, a history of multiple sunburns, fair complexion, the presence of multiple cutaneous nevi, and a personal or family history of melanoma or dysplastic nevi.The primary treatment of local and locoregional melanoma is surgical resection.Resection is indicated for patients with limited metastatic melanoma that is surgically resectable.
125Final Advice If you get stuck, remember these generalities: The only way to “cure” cancer includes surgery.Cancer that has spread to lymph nodes or beyond requires systemic treatment (i.e., chemotherapy).If you’re going to act, make it definitive (e.g., obtain a diagnosis, prefer curative treatments).You stand a good chance of guessing correctly.
