Seventy-eight patients underwent palliative resections for adenocarcinoma of the colon or rectum. The operative mortality was 6.4 per cent. The high morbidity rate of 43.5 per cent, mostly attributable to errors in operative technic and sepsis, could not be related to the extent of
tumor
spread. In fifty-nine patients long-term follow-up revealed a mean survival time of 12.4 months and a median of 9.1 months. Thirty-eight patients (64.4 per cent) survived six months, twenty patients (33.8 per cent) one year, seven patients two years, and one patient five years. Patients with only local extension of disease had the most favorable duration of survival. Hepatic or peritoneal involvement alone did not preclude long-term survival, but with the two combined the outlook was less favorable. There is a small group of patients with extensive
metastatic disease
who will not benefit from resection. Otherwise, adenocarcinoma of the colon or rectum with local or distant
metastases
should be resected when feasible.

With reference to the recent literature, a representation of case-history, therapy and prognosis of bronchial carcinoma is made. Inhalation of tar products by smoking, as well as predominantly occupational dust are the important etiological factors for the increase in bronchial carcinoma. Because of the long occult progression of the disease the diagnosis based on clinical symptoms is made very late. Only a greater effort in organisation and diagnostics permits an early detection in high-risk groups. Therapeutic success has remained constant since the sixties. Up to now only the consequent pre-operative selection of patients has been significant for improvement of surgical results. Five-year cures are more frequent after lobectomy than after pneumonectomy. In radiation therapy, the use of high-voltage gamma rays in contrast to conventional deep radio-therapy, has not brought any significant improvement. An additional intensive and individual care and follow-up of patients is of vital importance. The optimal curative radiation dose is 6000 rad. Particularly pre-operative irradiation is important to prepare some inoperable patients for curative surgery. Postoperative radiation therapy is also valuable for doubtful radical surgery and after exploratory thoracotomy. Palliative radiation therapy results in rapid disappearance of symptoms; with generalized disease or in suspicion for formation of
metastases
, chemotherapy should be preferred. This is particularly true for anaplastic, small and large cell carcinomas, and their rapidly growing
metastases
. In those cases, combination of polychemotherapy may decrease the
tumor
size and increase the length of remission. The prognosis depends on microscopic
tumor
type, stage of the disease, and therapy. Abnormal excretion of steroids and immunological disturbances are prognostic at the time of diagnosis.

The clinical records and imaging studies of 140 patients who had 57Co-bleomycin scans were reviewed. In 53% of the patients with known
tumor
at the time of examination, all clinically demonstrable lesions picked up cobalt. The success rate was particularly high in carcinoma of the lung (15 of 17) and gastrointestinal tract (12 of 17). The major role of cobalt bleomycin seems to be as an early screening test for
metastases
in patients with carcinoma of the lung, gastrointestinal tract, and uterus. The scan is most useful in demonstrating spread to the brain, liver, and adrenals.

Only patients with localized lung cancer benefit from curative resection. Curative radiotherapy is recommended in patients with a resectable
tumor
in whom surgery is precluded for medical reasons. Adjuvant preoperative or postoperative therapy of any type does not improve the results of surgery except in patients with Pancoast tumor. Therapy for nonlocalized tumors does not affect survival. Radiotherapy has a palliative effect in 50 to 75 per cent of patients presenting with symptoms from either a primary lesion or
metastases
and should therefore be recommended in symptomatic patients. The palliative effect of chemotherapy is limited in lung cancers other than small cell carcinomas. However, chemotherapy alone or in association with radiotherapy produces remarkable
tumor
regression and some improvement of survival in small cell carcinoma. The use of immunotherapy in the treatment of lung cancer is still under evaluation.

Levels of carcinoembryonic antigen (CEA), alpha-fetoprotein (AFP), ferritin and alpha 2-pregency associated glycoprotein (alpha-2-PAG) were determined in patients with confirmed lung cancer at the time of diagnosis and in serial determinations during and after radio- or chemotherapy. Whereas AFP levels were not elevated in patients with lung cancer, increased levels of CEA, ferritin and alpha-2-PAG were found in more than 50% of the patients. The results suggest that determination of CEA, ferritin and alpha-2-PAG in the serum of patients with lung cancer may be useful to detect
metastases
or recurrences and to monitor the results of treatment. Furthermore, in this study CEA and ferritin could be demonstrated in extracts of lung
tumor
tissues by specific antisera.

Ten patients with inoperable renal carcinoma underwent embolization of the renal artery. As embolic material homogenized autologous muscle was used. Besides conventional catheters introduced by the Seldinger technique also flow-directed balloon catheters were employed. The merely palliative purposes of embolization were staunching of otherwise untreatable hematuria in eight and reduction of
tumor
bulk in two cases. Bleeding could be stopped in all,
tumor
mass reduced in 6 patients as shown by control angiographies. There was always a recanalization of the renal arteries, the vascular tree, however, being much rarefied. Five patients died of the
metastatic cancer
within the first seven months after embolization, one patient three days after embolization due to phlegmonous retroperitoneal infection. Further complications consisted in flank pain, reversible rises of body temperature, blood pressure and serum creatinine levels. Thrombotic occlusion of deep veins occurred in two patients. The only true benefit of embolization for the patient consists in a relatively simple, fast and safe way to control an otherwise untreatable hemorrhage from inoperable renal carcinoma. Whether prolongation of survival can be reached remains doubtful in spite of a reduction of the
tumor
mass.

Five
tumor
markers can be simultaneously determined in the serum by radioimmunoassay: carcinoembryonal antigen (CEA), alpha-fetoprotein (alpha-FP), human chorionic gonadotropin (HCG), beta-subunit of HCG (beta-HCG) and kappa-casein. In a series of 935 healthy subjects, these antigens remain detectable or are detected within very precise limits. At the start of the clinical evolution of breast cancer, the incidence of pathological concentrations is increased as compared with the highest level observed in normal subjects. This high incidence is mainly due to a concomitant determination of CEA, kappa-casein, HCG and beta-HCG. The alpha-FP test is never positive, while the kappa-casein concentration is particularly high in the first clinical stages of breast cancer and with
metastases
. The concomitant determination of these
tumor
markers may be a biological element contributing to the diagnosis of
neoplasia
, although it is neither an absolute nor a specific criterium. Indeed, a pathological concentration of at least one antigen was observed in 5.5% of the subjects presenting with benign mastopathy. When
metastases
occur (25 patients), the incidence of pathological concentrations of at least one antigen increases: 88%, the absolute values of these levels increasing simultaneously. The determination of the antigen concentration therefore allows an evaluation of the extension of the disease. Surgical removal reduces the incidence of positivity of these antigens to 34%. Persistence of pathological levels seems to be related to a possibility of relapse or metastatic spreading. Finally, chemotherapy and radiotherapy applied on a
tumor
which is not excised, does not decrease the incidence of positivity of the tumoral markers, although their levels seem to fluctuate with the clinical evolution.

Serum AFP was determined serially by radioimmunoassay in 13 patients with ovarian germ cell tumors and in one patient with bilateral pure gonadoblastoma. There were 4 patients with pure dysgerminoma, one with pure endodermal sinus
tumor
(EST) and 8 with mixed germ cell tumors, all containing EST. The patients with dysgerminoma and gonadoblastoma had normal serum AFP at all times. All patients with tumors containing EST had raised serum AFP, although in most cases it was first determined between 1 and 3 weeks after operation and there was no evidence of
metastases
. Serum AFP became normal 5 to 7 weeks after operation and began to rise when disease recurred. Serum AFP determinations detected presence of recurrent disease long before it became detectable by other methods. Serum CEA was determined serially by radioimmunoassay in 8 of these patients, including 2 who dies with
metastases
, and was normal on all occasions.

Is seems indispensable, in consideration of the present investigation results, to revise our actual therapeutic conception for cancer therapy! While palliative cancer therapy was greatly successful, it was not possible to obtain any decisive improvement of cancer recovery rates (in relation to similar stages or
tumor
volumes), in spite of all the therapeutic endeavour through the last twenty or twenty-five years. From almost 3000 analyses of metastatic growth and from numerous other experimental or clinical observations results as an explication that surgical treatment itself, on certain conditions, may release a relatively great number of
metastases
. Thus, the failure of our therapeutical endeavor is programmed, too, by the treatment! Consequences for diagnostics, precautions and therapy are discussed.

57Co-Bleomycin (57Co-BLM) was used to visualize malignancies of the head and neck because it does not present the disadvantages of many other radiopharmaceuticals. In a series of 21 patients with 9 control subjects and 12 cases of tumors. 57Co-BLM showed a high and rapid uptake in primary site and
metastases
of malignant tumors of various histologic types, but not in benign tumors such as angiofibromas. Compared to 67Ga-citrate. 57Co-BLM has many advantages for
tumor
imaging in the areas of nose, pharynx and larynx: No background activity due to the concentration of 57Co-BLM in normal structures of the head and neck has ever been observed, as opposed to what happens with 67Ga-citrate. Furthermore, the blood clearance of 57Co-BLM is much more rapid than that of 67Ga-citrate, so that an early study may be performed in a 6-24 hr. interval instead of 48-72 hr. with 67Ga-citrate. 57Co-BLM scintigraphy is an easy, non-invasive and sensible diagnostic technique in determining the extent of malignant tumors in ORL patients.
