Polystyrene spheres with a range from chylomicron size up to 30 µ were injected into the peritoneal cavity of mouse, rat and cat, and were recovered from the regional lymph nodes. The largest recovered spheres in the mouse were 16.8 µ in diameter, in the rat and cat 24 µ. Inspection of the entire population of spheres recovered from lymph nodes 48 hours after intraperitoneal injection indicated that most of the fenestrations in the subperitoneal basement membrane are less than 5 µ in the mouse, and more than 5 µ in the cat. Fenestrations in the rat are intermediate between mouse and cat. The deductions as to fenestrations from inspection of the absorbed sphere populations is fairly well in accord with the histological picture in the mouse and cat. Many spheres reach the circulation and the larger ones are filtered out in the lungs, with resulting atelectasis.

India ink or graphite partides injected into an area of inflammation fail to disseminate to the tributary lymph nodes. When injected into a normal peritoneal cavity they rapidly appear in the retrosternal lymph nodes. When injected into an inflamed peritoneal cavity they are fixed in situ and fail to reach the regional lymph nodes. Graphite particles injected in the circulating blood stream enter an inflamed area both as free particles owing to increased capillary permeability and also as phagocyted material within leucocytes. Bacteria (B. prodigiosus) injected into inflamed tissue are fixed at the site of inflammation and fail to disseminate to the regional lymph nodes as readily as when injected into normal tissue. Bacteria (B. prodigiosus) injected at the periphery of an inflamed area do not readily penetrate into the site of inflammation. The experiments furnish evidence, in addition to that already provided, that fixation of foreign substances by the inflammatory reaction is primarily due to mechanical obstruction caused by a fibrin network and by thrombosed lymphatics at the site of inflammation. Bacteria (B. prodigiosus and B. pyocyaneus) injected intravenously rapidly enter an inflamed area. It is suggested that localization of bacteria in a locus minoris resistentiae may be explained as the result of increased capillary permeability with subsequent accumulation and fixation of bacteria from the blood stream at the point of injury.

The concept of biopsy of sentinel lymph node as the first lymph node in the pathway of lymphogenous tumor spread has been actively discussed over the past decades and has already taken its rightful place in breast and melanoma surgery. The goal of this method is to exclude vain lymphadenectomy in patients without solid tumor metastases in regional lymph nodes. In the era of minimally invasive and organ-saving operations interventions it seems obvious an idea to introduce a biopsy of sentinel lymph node in surgery of early gastric cancer. Meanwhile the complexity of lymphatic system of the stomach and the presence of so-called skip metastases are factors limiting the introduction of a biopsy of sentinel lymph node in stomach cancer. This article presents a systematic analysis of biopsy technology of signaling lymph node as well as its safety and oncological adequacy. Based on literature data it seems to us that the special value of biopsy of sentinel lymph nodes in the future will be in the selection of personalized surgical tactics for stomach cancer.

Objective: to justify the expediency of the surgical stage as a part of the combination treatment for stage IIA-IIIB cervical cancer. Materials and methods. The study included 343 women with stage IIA-IIIB cervical cancer treated from 2013 to 2016 with mandatory follow-up for at least 2 years. Patients were divided into 2 groups. The first group included 214 patients who received a combination treatment. At the first stage, neoadjuvant chemoradiation therapy was performed (remote radiation therapy 5 days a week with radio modification with Cisplatin once a week at a dose of 40 mg/m2). After evaluating the effect, patients were subjected to surgical treatment or continued chemoradiotherapy. The second group (n = 129) received standard combined radiation therapy. Various schemes of combination and complex treatment and standard combined radiation therapy were evaluated using the indices of general and relapse-free survival. Results. The proposed scheme for the combination therapy for patients with locally advanced cervical cancer showed significantly higher survival rates at all the analyzed stages. For the combined treatment group with complete cytoreduction, the two-year overall and relapse-free survival with stage IIA is 94.1% vs. 82.4%, with IIB 90.8% vs. 80.3%, with IIB 87.5% vs. 75%, with IIB with metastatic lesion of regional lymph nodes 85% vs. 70%. For the second group, two-year overall and relapse-free survival with stage IIA 75% vs. 50%, with IIB 70.9% vs. 56.3%, with IIB 59.1% vs. 40.9%, with IIB with metastatic lesion of regional lymph nodes 62.2% and 40.5%. The advantages of this approach are most clearly seen within patients with metastatic lesions of regional lymph nodes (85% vs. 62% accordingly). Conclusion. Cytoreductive surgery in combination with the combination therapy allows to achieve a significant increase in overall and relapse-free survival for patients with locally advanced cervical cancer compared with standard treatment programs.
