Final version of the American Joint Committee on Cancer staging system for cutaneous melanoma.

PURPOSE: To revise the staging system for cutaneous melanoma under the auspices of the American Joint Committee on Cancer (AJCC). MATERIALS AND METHODS: The prognostic factors analysis described in the companion publication (this issue), as well as evidence from the published literature, was used to assemble the tumor-node-metastasis criteria and stage grouping for the melanoma staging system. RESULTS: Major changes include (1) melanoma thickness and ulceration but not level of invasion to be used in the T category (except for T1 melanomas); (2) the number of metastatic lymph nodes rather than their gross dimensions and the delineation of clinically occult (ie, microscopic) versus clinically apparent (ie, macroscopic) nodal metastases to be used in the N category; (3) the site of distant metastases and the presence of elevated serum lactic dehydrogenase to be used in the M category; (4) an upstaging of all patients with stage I, II, and III disease when a primary melanoma is ulcerated; (5) a merging of satellite metastases around a primary melanoma and in-transit metastases into a single staging entity that is grouped into stage III disease; and (6) a new convention for defining clinical and pathologic staging so as to take into account the staging information gained from intraoperative lymphatic mapping and sentinel node biopsy. CONCLUSION: This revision will become official with publication of the sixth edition of the AJCC Cancer Staging Manual in the year 2002.

A new American Joint Committee on Cancer staging system for cutaneous melanoma.

The Melanoma Staging Committee of the AJCC has proposed major revisions of the melanoma TNM and stage grouping criteria. The committee members represent most of the major cooperative groups and cancer centers worldwide with a special interest in melanoma; the committee also collectively has had clinical experience with over 40,000 patients. The new staging system better reflects independent prognostic factors that are used in clinical trials and in reporting the outcomes of various melanoma treatment modalities. Major revisions include 1) melanoma thickness and ulceration, but not level of invasion, to be used in the T classification; 2) the number of metastatic lymph nodes, rather than their gross dimensions, the delineation of microscopic versus macroscopic lymph node metastases, and presence of ulceration of the primary melanoma to be used in the N classification; 3) the site of distant metastases and the presence of elevated serum LDH, to be used in the M classification; 4) an upstaging of all patients with Stage I,II, and III disease when a primary melanoma is ulcerated; 5) a merging of satellite metastases around a primary melanoma and in-transit metastases into a single staging entity that is grouped into Stage III disease; and 6) a new convention for defining clinical and pathologic staging so as to take into account the new staging information gained from intraoperative lymphatic mapping and sentinel lymph node biopsy. The AJC Melanoma Staging Committee invites comments and suggestions regarding this proposed staging system before a final recommendation is made.

Two hundred eighty-six cases of parathyroid carcinoma treated in the U.S. between 1985-1995: a National Cancer Data Base Report. The American College of Surgeons Commission on Cancer and the American Cancer Society.

BACKGROUND: In combination with other Commission on Cancer programs, the National Cancer Data Base (NCDB), a national electronic registry system currently capturing > 60% of incident cancers in the U. S., offers a working example of voluntary, accurate, cost-effective "outcomes management" on a both a local and national scale. In addition, it is proving to be of particular value in capturing clinical information concerning rare cancers. METHODS: For accession years 1985-1995, the NCDB captured prospectively collected demographic, stage, treatment, and outcome information for a national hospital-based sample of 286 parathyroid carcinoma cases (0.005% of the total NCDB cancer cases). This report describes clinical and demographic features as well as patterns of care and 5-year and 10-year relative survival rates. RESULTS: The NCDB's 10-year accrual of parathyroid carcinoma cases exceeded the cumulative number reported in the English literature though 1991. Gender distribution was equal. The authors were unable to detect any disproportionate clustering by race, income level, or geographic region. Treatment overwhelmingly was surgical. The data from the current study suggest that neither tumor size nor lymph node status are significant prognostic factors. Overall relative survival at 5 years and 10 years was 85.5% and 49.1%, respectively. CONCLUSIONS: At 5 years of follow-up, and possibly beyond, neither tumor size nor lymph node status were found to be significant prognostic factors and basing a staging system on them would be useless. Although complete, en bloc resection of all tumor represents the best opportunity for cure, a substantial proportion of patients fail to receive such treatment. The authors speculate that the rarity of this condition and late intraoperative recognition occasionally prevent optimal treatment. [See editorial on pages 378-80, this issue.]

A National Cancer Data Base report on 53,856 cases of thyroid carcinoma treated in the U.S., 1985-1995 [see commetns].

BACKGROUND: The National Cancer Data Base (NCDB) represents a national electronic registry system now capturing nearly 60% of incident cancers in the U. S. In combination with other Commission on Cancer programs, the NCDB offers a working example of voluntary, accurate, cost-effective "outcomes management" on a both a local and national scale. In addition, it is of particular value in capturing clinical information concerning rare cancers, such as those of the thyroid. METHODS: For the accession years 1985-1995, NCDB captured demographic, patterns-of-care, stage, treatment, and outcome information for a convenience sample of 53,856 thyroid carcinoma cases (1% of total NCDB cases). This article focuses on overall 10-year relative survival and American Joint Committee on Cancer (AJCC) (3rd/4th edition) stage-stratified 5-year relative survival for each histologic type of thyroid carcinoma. Care patterns also are discussed. RESULTS: The 10-year overall relative survival rates for U. S. patients with papillary, follicular, Hürthle cell, medullary, and undifferentiated/anaplastic carcinoma was 93%, 85%, 76%, 75%, and 14%, respectively. For papillary and follicular neoplasms, current AJCC staging failed to discriminate between patients with Stage I and II disease at 5 years. Total thyroidectomy +/- lymph node sampling/dissection represented the dominant method of surgical treatment rendered to patients with papillary and follicular neoplasms. Approximately 38% of such patients receive adjuvant iodine-131 ablation/therapy. At 5 years, variation in surgical treatment (i.e., lobectomy vs. more extensive surgery) failed to translate into compelling differences in survival for any subgroup with papillary or follicular carcinoma, but longer follow-up is required to evaluate this. NCDB data appeared to validate the AMES prognostic system, as applied to papillary cases. Younger age appeared to influence prognosis favorably for all thyroid neoplasms, including medullary and undifferentiated/anaplastic carcinoma. NCDB data also revealed that unusual patients diagnosed with undifferentiated/anaplastic carcinoma before age of 45 years have better survival. CONCLUSIONS: The NCDB system permits analysis of care patterns and survival for large numbers of contemporaneous U. S. patients with relatively rare neoplasms, such as thyroid carcinoma. In this context, it represents an unsurpassed clinical tool for analyzing care, evaluating prognostic models, generating new hypotheses, and overcoming the volume-related drawbacks inherent in the study of such neoplasms.

Breast masses in women treated for childhood cancer: incidence and screening guidelines.

BACKGROUND: The authors' aims were to define the frequency, characteristics, and methods of detection of breast masses in young women treated for childhood cancer and to develop screening guidelines for the growing population of long term survivors. METHODS: The authors reviewed medical records of all female patients treated for malignancy at a childhood cancer center over a 34-year period to identify those who developed a breast mass and to determine the cumulative incidence of breast cancer as a second primary cancer. RESULTS: A breast mass was identified in 66 patients who had been diagnosed with a malignancy at a median age of 13.8 years (range, 0.4-24.4 years). Masses were initially detected by breast self-detection in 32 and clinical examination in 28; the method of detection was unknown in 6 cases. Breast lesions were benign in 41 patients and malignant in 26; 1 patient had both a benign and a malignant lesion. Of the 26 malignant masses, 14 represented metastases of the primary malignancy and 12 were primary breast cancers as second primary cancers. The median interval to a primary breast cancer as a second primary cancer was 13.6 years (range, 9.2-24.4 years), and the median age at detection was 27.7 years (range, 12.5-43.1 years). The 25-year cumulative incidence of primary breast cancer as a second primary cancer in this cohort was 1.7% (95% CI, 0.4%-2.9%). This represented a 20-fold increase (95% CI, 10-36) over the expected incidence in age-matched and race-matched controls. CONCLUSIONS: Young women treated for childhood cancer have a significantly increased risk of breast cancer compared with age-matched controls. For this group of patients, the authors recommend patient education regarding this risk and the importance of properly conducted self-examination as the foundation of breast cancer screening. In addition, clinical and mammographic screening should be instituted at a younger age and performed more frequently than recommended for the general population of women.

The National Cancer Data Base report on recent hospital cancer program progress toward complete American Joint Committee on Cancer/TNM staging.

BACKGROUND: American Joint Committee on Cancer (AJCC) staging procedures were first published in 1977. Since 1991 the Commission on Cancer (COC) has required AJCC staging of all nonpediatric cancers. The National Cancer Data Base (NCDB) encouraged recording of AJCC staging through analyses of selected aspects of staging completeness. We reviewed the trend toward the adoption of routine AJCC staging by hospitals for the 5-year period 1990-1994. METHODS: NCDB reports for nearly 2 million stageable cancers diagnosed from 1990 through 1994 were examined with emphasis on the hospital cancer program environment. Staging was complete if the hospital submitted stage codes for > or =90% of stageable cases or absent if stage codes were submitted for <5%. Hospitals were classified by ownership and type of cancer program. Regional staging practices also were reviewed. RESULTS: Overall staging increased from 78% to 88%, with increases for every site except carcinomas of the skin, cancers of the extrahepatic bile ducts and urethra, melanoma of the eyelid, and retinoblastoma The percent of hospitals staging completely increased from 49% to 61%, and the percent not routinely staging decreased from 6% to 3%. Complete staging increased in all hospital categories except For-Profit. The trend toward complete staging was uneven among states and regions. CONCLUSIONS: Hospital staging policies were affected by activities of the AJCC, COC, NCDB, clinical protocol procedures, and state policies. The varied completeness of staging at the hospital level by state, region, and type of hospital indicates that the adoption of routine staging is ongoing.

Comparison of primary osteosarcoma of flat bones with secondary osteosarcoma of any site.

BACKGROUND: The authors hypothesized that the outcomes for young patients who present with primary osteosarcoma of flat bones or secondary osteosarcoma after other primary malignancies are similar because the sites of these tumors rarely makes them amenable to complete surgical resection. METHODS: The authors reviewed their experience with 27 patients with primary osteosarcomas involving flat bones and 18 patients with secondary osteosarcomas of any site, evaluating treatment, metastatic patterns, and outcome. RESULTS: Eleven of the 27 primary osteosarcomas and 10 of the 18 secondary osteosarcomas were at least partially resectable at the time of initial diagnosis. At last follow-up, 10 of the 27 patients with primary flat bone osteosarcoma were alive, eight of whom were disease free. Three of 18 with the secondary osteosarcoma patients were alive, including one with locally recurrent disease after recent disease resections. Chemotherapy with single or combinations of agents rarely yielded responses for primary flat bone or secondary osteosarcomas. CONCLUSIONS: Outcome for both groups of patients was poor due to metastases and failure of local control. Sixteen of the 27 patients with primary osteosarcoma of flat bones died of their tumor; an additional patient died of doxorubicin-related cardiomyopathy and had microscopic disease in the primary site at autopsy. Thirteen of the 18 patients with secondary osteosarcoma died of their second metastatic cancer, 2 additional patients died of doxorubicin-related cardiomyopathy/coccidioidomycosis, and another of acute renal toxicity.

Second malignant neoplasms occuring in survivors of osteosarcoma.

BACKGROUND: Second malignant neoplasms have been noted infrequently in survivors of osteosarcoma treated before 1970. METHODS: For the above reason, the authors surveyed their patients to determine the actuarial incidence and relative risk of second malignancies among patients treated with adjuvant chemotherapy for osteosarcoma. RESULTS: Between March 1962 and March 1996, 334 patients received chemotherapy for newly diagnosed primary or metastatic osteosarcoma. Of these patients, 47 presented with metastases, 14 had multifocal osteosarcoma, and 273 had localized disease. Nine patients developed second malignant neoplasms 0.45-17.8 years (median, 6.3 years) after receiving definitive surgery and adjuvant chemotherapy for primary osteosarcoma; 2 of these patients had pulmonary metastasectomies before receiving adjuvant chemotherapy. The second neoplasms comprised two cases of malignant fibrous histiocytoma and one case each of melanoma, glioblastoma multiforme, chondrosarcoma, and carcinoma of the breast: stomach, colon, rectum. The overall 10-year cumulative incidence of second malignancies was 2% +/- 1%; by comparison, this rate was 2% +/- 1% for patients with localized osteosarcoma but was 8% +/- 5% (P = 0.15) for those who presented with metastatic disease. CONCLUSIONS: Since the advent of successful adjuvant chemotherapy, more patients are surviving primary osteosarcoma; therefore, the number of osteosarcoma patients who develop second malignancies can be expected to increase. Recognition of osteosarcoma patients who are members of families with Li-Fraumeni syndrome may lead to earlier intervention for these individuals.

The National Cancer Data Base report on completeness of American Joint Committee on Cancer staging in United States cancer facilities. The American College of Surgeons Commission on Cancer and the American Cancer Society.

BACKGROUND: American Joint Committee on Cancer (AJCC) staging is increasingly accepted as a prognostic standard for cancer management. The Commission on Cancer requires approved cancer programs to use AJCC staging for all cancers. Previous studies document increasing use of AJCC staging by hospitals with cancer programs. This review examines programmatic and clinical factors affecting AJCC staging completeness. METHODS: The data are registry records submitted to the National Cancer Data Base (NCDB) for cases diagnosed during 1993 or, for comparison, 1988. RESULTS: The mean facility staging rate was 87% in 1993, up from 65% in 1988. Approximately 64% of facilities staged greater than 90% of their stageable cases; 3% staged less than 5%. Even facilities with "complete" staging implementation were unable to stage substantial portions of some sites. Accessibility of tumor and overall prognosis affected the choice between pathologic and clinical staging. Staging completeness and the mix of pathologic and clinical staging also differed by state of the reporting facility. CONCLUSIONS: AJCC staging use is high among common tumors for which treatment is dependent upon stage of disease. However, if accurate staging is not expected to affect the treatment or outcome of the case or the overall outcome is poor, staging is less frequently recorded.

Principles of management of basal and squamous cell carcinoma of the skin.

There are a number of options available to the physician for the primary management of basal cell and squamous cell carcinoma of the skin. The most commonly used treatment modalities are primary resection, radiation therapy, and Mohs' micrographic surgery. Although each of these modalities can be used to treat most skin cancers in a variety of settings, each of these forms of cancer treatment is more appropriate in some settings and less appropriate in others. The role of each mode of therapy is discussed, based on effectiveness for cure, short and long term side effects, and cost of treatment. The appropriate role of the physician treating skin carcinoma is to choose the most effective treatment based on the above criteria and not to make the tumor fit any particular treatment modality.

Chest wall resection for Ewing's sarcoma of the rib: an unnecessary procedure. 1988. Updated in 1995.

Approximately 10% of all cases of Ewing's sarcoma arise from a rib. Conventional management has included chest wall resection (3 or more ribs) and radiation therapy. These forms of therapy have led to complications such as scoliosis and local deformity. The addition of radiation therapy can result in damage to the lung and adjacent viscera and also potentiate pulmonary restrictive disease. Between 1971 and 1978, 9 patients were treated with surgery, radiation therapy, and combination chemotherapy (three- or four-drug regimen). Only 2 patients (22%) survive. Since 1979, 14 patients were entered into a new protocol consisting of sequential induction chemotherapy, followed by delayed surgical resection whenever feasible. Three patients had complete resection of their primary lesion at onset. Initially, 7 patients had either biopsy (N = 4) or incomplete chest wall resection N = 3). All 4 patients with biopsy only at diagnosis had excellent responses to induction chemotherapy, allowing delayed resection of the involved rib without chest wall resection. Overall, 12 of 14 patients (86%) treated since 1979 survive, with only 2 receiving radiation therapy for residual disease in the primary rib site.

Indications for hemiscrotectomy in the management of genitourinary tumors in children.

In the last 30 years at St Jude Children's Research Hospital, 10 boys have undergone hemiscrotectomy for primary testicular tumors or paratesticular rhabdomyosarcoma. Indications for this procedure were scrotal contamination and positive or uncertain surgical margins. Residual tumor was found in only one specimen. There were four complications in the study group. Two patients had complications directly attributable to the hemiscrotectomy, and in one patient this caused a delay in treatment. Preoperative imaging was performed in three patients. This has not been helpful in evaluating residual masses and is not indicated. Based on the authors' experience and a review of the literature, there are a number of indications for hemiscrotectomy in the management of genitourinary tumors in children. Controversies regarding some of these indications should be discussed with the families of these patients during preoperative counseling.

Barriers to clinical trials. Part I: Reimbursement problems.

Most of the major clinical advancement in cancer treatment has been provided by cancer clinical trials. Approximately 60% of clinical trials are conducted in the community treatment setting and approximately 40% in academic and cancer centers. The cost of these trials are borne by a combination of third-party reimbursement for the cancer care and institution and research study support for the specific cost of the research trial. With the increasing emphasis on cost control, managed cancer care, and health care reform, there is evidence of increased resistance and even denial of third-party insurance carriers for the usual cancer care done in association with cancer clinical trials. If this issue is not specifically addressed in today's managed care environment or in proposed health care reform, there will be a severe barrier to future cancer clinical research and an associated decrease in the identification and evaluation of new and better cancer treatment.

Breast cancer in elderly women.

With the aging of the American population, more older women are being diagnosed with breast cancer. With the possible exception of women under 40 years of age, there is no clear evidence of a biologic or clinical difference between breast cancer in younger and older aged groups. Breast cancer is diagnosed at a more advanced stage in older women. Elderly women with breast cancer frequently are treated with less than standard therapy and are less often included in clinical trials. With the exception of specific comorbid conditions that preclude anesthesia and surgery, older women tolerate breast surgery as well as younger women. The results of good surgical and adjuvant therapy for elderly women are as good as those for younger women. Older women with breast cancer deserve the most effective screening, diagnosis, and surgical treatment available.
