在文檔中 外 科 部 (頁 30-36)

一、 History:

1. Family history of cancer.

2. Local symptoms; Hematuria, dysuria, frequency.

3. Other symptoms: Flank pain, bone pain, sciatica, peripheral edema, weight loss.

4. Carefully record nature and date and pathology finding relative to all previous treatments.

二、 Past and social history:

1. Occupation related Carcinogen exposure, time, durations.

2. Smoking habit: Amount and duration.

3. Faimily factors: Parents occuption, or special prefer food intake.

4. Analgesico or herb drugs medication (Dose and duration) 三、 Physical examination:

Palpation of neck, abdomen, groins, urethra and pelvic examination (rectal in males;

rectal and pelvic examination in females.) 四、 Special laboratory studies:

Urine cytology, initially and immediately post treatment and at appropriate intervals during follow up.

五、 Tumor spreading:

1. Regional Lymph Nodes. The regional lymph nodes are the nodes of the true pelvis, which essentially are the pelvic nodes below the bifurcation of the common iliac arteries.

The significance of regional lymph node metastasis in stasins bladder cancer lies in the number and size and not in whether metastasis is unilateral or contralateral.

Regional nodes include:

Hypogastric Obturator

Iliac (internal, external, NOS) Perivesical

Pelvic, NOS

Sacral (lateral, sacral promontory [Gerota's]) Presacral

The common iliac nodes are considered sites of distant metastasis and should be coded as Ml.

2. Metastatic Sites. Distant spread to lymph nodes, lung, bone, and liver is most common.

六、 Clinical Staging:

Primary tumor assessment includes bimanual examination under anesthesia before and after endoscopic surgery (biopsy or transurethral resection) and histologic verification of the presence or absence of tumor when indicated. Bimanual examination following endoscopic surgery is an indicator of clinical stage. The

finding of bladder wall thickening, a mobile mass, or a fixed mass suggests the presence ofT3a, T3b, and T4b disease, respectively. Add "m" for multiple tumors.

Add "is" to anv T to indicate associated carcinoma in situ.

Appropriate imaging techniques for lymph node evaluation should be used. When indicated, evaluation for distant metastases includes imaging of the chest, biochemical studies, and isotopic studies to detect common metastatic sites.

Computed tomography or other modalities may subsequently be used to supply information concerning minimal requirements for staging. The primary tumor may be superficial or invasive and can be partially or totally resected with sufficient tissue from the tumor base for evaluation of full depth of tumor invasion. Visually adjacent cystoscopically normal mucosa should be considered for biopsy; urinary cytology and pyelography are important.

七、 Pathologic Staging:

Microscopic examination and confirmation of extent is required. Total cystectomy and lymph node dissection generally are required for this staging. Laterality does not affect the N classification.

DEFINITION OF TNM 1. Primary Tumor (T)

TX Primary tumor cannot be assessed T0 No evidence of primary tumor Tis Carcinoma in situ: "flat tumor"

Tl Tumor invades subepithelial connective tissue T2 Tumor invades muscle

四、 Laboratory Studies:

1. I.V.P.

2. Retrograde pyelograms.

3. CT Scan of abdomen when indicated for staging work up.

六、 Possible spreading:

1. Regional Lymph Nodes. The regional lymph nodes are:

For Renal Pelvis:

Renal hilar Paracaval Aortic

Retroperitoneal For Ureter:

Renal hilar

Iliac (common, internal [hypogastric], external) Paracaval

Peri-ureteral Pelvic, .KgS

Any amount of regional lymph node metastasis is a poor prognostic finding and outcome is minimally influenced by the number, size, or location of the regional nodes which are involved.

2. Metastatic Sites. Distant spread to lung, bone, or liver is most common.

七、 Staging:

Clinical Stagins. Primary turmor assessment includes radiographic imaging, usually by intravenous and/or retrograde pyelography. Computerized tomography

is desirable and tissue biopsy through the ureterocope may be performed if feasible.

Urine cytology may help determine tumor grade if tissue is not available. Staging of tumors of the renal pelvis and ureter is not influenced by the presence of any concomitant bladder tumors which may be identified.

八、 Pathologic Staging.

Pathologic staging depends upon histologic determination of the extent of invasion by the primary tumor. Treatment frequently requires resection of the entire kidney, ureter, and a cuff of bladder surrounding the ureteral orifice.

Appropriate regional nodes may be sampled. A more conservative surgical resection may be performed, especially with distal ureteral tumors or in the presence of compromised renal function.

Endoscopic resection through a ureteroscope or a percutaneous approach may be used in some circumstances. Submitted tissue may be insufficient for accurate histologic examination and pathologic staging. Laser or electrocautery coagulation or vaporization of the tumor may be performed, especially if the visible appearance is consistent with a low grade and low stage tumor. Under these circumstances, there may be no material available for histologic review.
