Some of these patients address the doctors in locally advanced stages, sometimes without the possibility to perform resection. The challenge of the multimodal oncologic treatment of those patients is to obtain conversion towards resection, and also the decrease of the local recurrence, thus ensuring the increase of the long-term survival, targets which are often difficult to obtain.
Colorectal Cancer Debate: First Line BRAF V600E - Targeted Triplet
We present the case of a year-old patient with locally advanced rectal cancer, who benefitted from multimodal treatment: neo-adjuvant colorectal cancer targeted therapy and radiotherapy, and also from surgical intervention. O parte dintre aceşti pacienţi se prezintă în stadii avansate local, uneori nerezecabile.
Colorectal cancer targeted therapy
Provocarea tratamentului oncologic multimodal al acestor pacienţi este de a obţine conversia către rezecabilitate, precum şi scăderea incidenţei recurenţei locale, asigurând astfel creşterea supravieţuirii la distanţă, deziderate ce sunt adesea greu de obţinut. Vă prezentăm cazul unei paciente în vârstă de 54 de ani, diagnosticată cu neoplasm rectal local avansat, ce a beneficiat de tratament multimodal chimio-radioterapic neoadjvant şi adjuvant, precum şi chirurgical complex.
A retrospective study of SEER CRC registry showed an increase in the incidence of rectal cancer in patients under 50 years of age 1,2,3. The most common disorders are Lynch syndrome and familial adenomatous paraziti abstract 1,2.
Important improvements in the outcomes of patients with rectal cancer have occurred over the past 30 years. Advances in surgical pathology, refinements in surgical techniques and colorectal cancer targeted therapy, new imaging modalities, and the widespread use of neoadjuvant therapy have all contributed to these colorectal cancer targeted therapy.
Many new systemic treatment options have become colorectal cancer targeted therapy for locally advanced rectal cancers, including: additional chemotherapeutic agents and targeted therapies vascular-endothelial growth factor and epidermal growth factor receptor inhibitors which can be added to neoadjuvant and adjuvant regimens or given in combination with radiotherapy as radio-sensitizing agents.
An important aim is to treat so that the risk of residual disease colorectal cancer targeted therapy the pelvis, frequently causing a disabling local recurrence, is very low. We report a case of a year-old patient diagnosed with locally advanced rectal cancer and treated with a multimodal approach.

Treatment sequence Case report In Novembera year-old female, smoker patient, presented at the primary care physician accusing rectal bleeding, pain and perianal abscess. A colonoscopy was performed and she was diagnosed through a biopsy with rectal adenocarcinoma.
The CT scan performed showed a locally advanced rectal tumor - cT4cN1Mx, with a suspicion of paraaortic lymph node metastases lymphadenopathy around 8 mm - Figure 1. Clinical examination revealed no pathological elements, with a good performance status and biologically within normal limits.
The tumor board decided that the best treatment sequence was colorectal cancer targeted therapy chemo-radiotherapy and then surgery. Colorectal cancer targeted therapy protective ileostomy was performed Figure 2.
The response evaluation CT scan showed a small regression of the primary tumor and increased paraaortic lymph nodes. An MRI performed after 6 months showed an important response to treatment with a conversion to resectability, and surgery was indicated Figure 4.
The patient underwent radical surgery in January total hysterectomy with bilateral ovariectomy, rectum amputation and colpectomy. During chemotherapy, mild gastrointestinal nausea, vomiting, diarrhea and hematological toxicity was observed and the patient experienced for a short period of time fatigue, asthenia, muscle weakness, numbness in limbs.
During this period the patient presented dysuria and her chemistry work-up revealed increased serum creatinine 5. A urine summary, bacteriological examination of urine and abdominal ultrasound determined that she developed a urinary tract infection with grade 2 proteinuria and the administration of Bevacizumab was discontinued for a short period of time, until her biological parameters returned to normal ranges Figure 5.

Regarding prognostic factors in this case - stage IV rectal cancer, with a high risk of recurrence, paraaortic lymph nodes involvement, side effects of the treatment grade 2 proteinuria that can lead to discontinuation of Bevacizumab - we can establish a poor prognostic for this patient.

Hematological toxicity hemoglobin and increase of serum creatinine Discussions The sequence is the most important multimodal therapy in rectal cancer.
In this case, the choice of colorectal cancer targeted therapy radio-chemotherapy and targeted therapy resulted in partial remission and conversion to resectability of the tumor. Prevention from local failures with the severe morbidity which may accompany them is very important.
The prognosis is also influenced by late effects of treatment toxicity and radio-chemotherapy, with the patient having gastrointestinal toxicity, hematologic and even proteinuria during treatment 1,2,4,7, In a retrospective study published in by Hsueh-Ju Lu, with a total of 4, newly diagnosed CRC patients who were enrolled, the authors aimed to assess the prognostic role of visible paraaortic lymph nodes PALNs.
