Chances Of Developing Metastatic Prostate Cancer

Clinical Case presentation – “Clinical lymph node metastatic prostate cancer (cN1)”

About 50% of men diagnosed with local prostate cancer will get metastatic cancer during their lifetime. Finding cancer early and treating it can lower that rate.

A small percentage of men arent diagnosed with prostate cancer until it has become metastatic. Doctors can find out if its metastatic cancer when they take a small sample of the tissue and study the cells.

Stage 1 Prostate Cancer

Stage 1 is the least advanced form of prostate cancer. Cancer in this stage is small and hasnt spread past the prostate gland. Its characterized by a PSA of less than 10 ng/mL, a grade group score of 1, and a Gleason score of 6.

Stage 1 prostate cancer has a 5-year survival rate of nearly 100 percent.

Types Of Imaging Studies

If your doctor suspects your cancer might be spreading, they will likely order more imaging tests. A common imaging workup may include a bone scan and a CT scan of the abdomen and pelvis. An MRI might be done as well. Some research centers are also using magnetic MRIs or PET scans to further refine the staging of prostate cancer.

Correlation Of Dominant Tumor Location And Positive Lymph Node Location

On review of RP specimens, 50 dominant tumor masses were located in the right lobe, 44 in the left lobe and 31 in bilateral lobes. Fifteen of 50 right lobe dominant cases showed positive LNs on the left side . Conversely, 18 of 44 left lobe dominant cases showed positive LNs on the right side .

15/50 right lobe dominant cancers had positive lymph nodes in the left pelvis 18/44 left lobe dominant cancers showed positive lymph nodes in the right pelvis .

Unifocal large volume high grade tumor with lymph node metastasis only on the right side Multifocal small volume low grade tumor with bilateral lymph node metastases Anterior dominant, relatively small volume grade 4+3=7 tumor with lymph node metastasis on the right side.

Dominant tumors were located in posterior/posterolateral prostate in 102 , both anterior and posterior in 18 and anterior only in 5 cases, respectively. Sixty dominant RP tumors extended from apex through base, 45 cases were located primarily in the apex to mid gland and 19 cases in the mid to base. Thirteen of 16 cases without EPE or SVI had dominant tumors localized to the apex-mid prostate.

A Comparison Of Broad Copy

File:Diagram showing prostate cancer that has spread to the lymph nodes ...

We used the Illumina BeadChip to determine the genome-wide copy-number profiles of 48 samples collected from 6 patients with metastatic prostate cancer . 37 were inferred as approximately diploid, 10 were found with to have an average ploidy close to 3 and 1 sample had a tetraploid genome . Primary and metastatic disease sites were found to have examples of both diploid and non-diploid genomes.

Figure 1

Heat map of gene copy numbers across chromosomes. The copy number profiles were consistently fragmented across samples to allow comparative analyses. Loess regression of the CNA profiles of the sampled clones adjusted for total ploidy. The value of 0 of the y axes represents no increase/decrease compared to a diploid genome.

The analysis of the Euclidean distance across copy-number profiles surprisingly indicated that the profiles of bone metastases were generally more related with the primary prostate tumour populations than with the lymph node metastases. The large separation between lymph and bone metastases using this measure suggests they are distinct at a genomic level.

Comparative Analyses Of Copy Number Profiles

For identifying the potential driver CNAs across transitions between histo-pathological categories, we selected for each evolutionary hierarchy the representative ancestral population for each category with the criteria that it should originate all of sampled clones belonging to such category. For each transition between histo-pathological categories, we obtained the increase/decrease CNA profile subtracting two consecutive representatives . Then, we consistently fragmented the resulting increase/decrease CNA profiles to allow direct comparison and tested each genomic fragment for differences across histo-pathological categories using analysis of variance . All changes with a false-discovery corrected p-value < 0.25 are reported in .

Stage Iv Prostate Cancer

When prostate cancer spreads, its often found in nearby lymph nodes. If cancer has reached these nodes, it also may have spread to other lymph nodes, the bones, or other organs.

When cancer spreads from its original place to another part of the body, the new tumor has the same kind of abnormal cells and the same name as the primary tumor. For example, if prostate cancer spreads to bones, the cancer cells in the bones are actually prostate cancer cells. The disease is metastatic prostate cancer, not bone cancer. For that reason, its treated as prostate cancer, not bone cancer. Doctors call the new tumor distant or metastatic disease.

The cancer has spread beyond the prostate.

  • Stage IVA: The cancer has spread to the regional lymph nodes.
  • Stage IVB: The cancer has spread to distant lymph nodes, other parts of the body, or to the bones.

Dna Extraction And Snp Chip

Genomic DNA was extracted using the QIAamp DNA FFPE Tissue Kit according to manufacturers instructions. Briefly, we placed the macrodissected tissue in 180l ATL buffer with 20l proteinase K and performed RNAse digestion and genomic DNA purification by column chromatography with elution in 100l nuclease-free water. We restored 200ng of genomic DNA per sample using the Infinium HD FFPE Restore Protocol and Zymo Research DNA Clean & Concentrator as required. For each sample, all 8l of restored DNA was used as input for the Infinium HD FFPE Assay . We linearly amplified the DNA across the whole genome and fragmented it enzymatically. The resulting product was hybridised to the Illumina HumanOmniExpress-FFPE-12 v1.0 BeadChip and incubated at 48°C for 1624hrs. Imaging was performed using the Illumina iScan system and intensity values derived for each bead type. LogR Ratios and B allele frequencies were calculated from the intensity data using GenomeStudio v2010.3 with Genotyping module 1.8.4 software and the HumanOmniExpress-12v1 G FFPE manifest cluster file. Overall, we achieved high SNP call rates with a median of 98.35% . The median standard deviation of the LogR Ratio values was 55%. The goodness of fit of the predicted aberrant fractions was always above 0.76 with a mean of 0.91.

Abstract

Prostate cancer is the most common cancer in men, often presenting with regional lymph node or bone metastasis and rarely with supradiaphragmatic lymph node involvement. Most metastatic cancers involving the cervical lymph nodes are from cancers of the upper aerodigestive tract. In this report, we describe two cases with cervical lymph node enlargement due to metastatic prostate cancer as the initial clinical presentation: a 43-year-old male, initially misdiagnosed with a tumor of the upper aerodigestive tract and an 87-year-old male with right lobe pneumonia and cervical lymph node enlargement, initially attributed to be an acute inflammatory lymph node reaction. To the best of our knowledge, there are less than 50 cases reported in the literature of adenocarcinoma of prostate metastatic to the cervical lymph nodes and only one case presenting in men younger than 45 years. The authors intend to highlight the importance of digital rectal exam and PSA test in case of persistent left cervical lymph node enlargement, including men younger than 45 years of age.

Background: Traditional clinical target volume definition for pelvic radiotherapy in prostate cancer consists of large volumes being treated with homogeneous doses without fully utilizing information on the probability of microscopic involvement to guide target volume design and prescription dose distribution.

Methods: We analyzed patterns of nodal involvement in 75 patients that received RT for pelvic and paraaortic lymph node metastases from prostate cancer in regard to the new NRG-CTV recommendation. Non-rigid registration-based LN mapping and weighted three-dimensional kernel density estimation were used to visualize the average probability distribution for nodal metastases. As independent approach, the mean relative proportion of LNs observed for each level was determined manually and NRG and non-NRG levels were evaluated for frequency of involvement. Computer-automated distance measurements were used to compare LN distances in individual patients to the spatial proximity of nodal metastases at a cohort level.

Correlation With Dominant Tumor Location

Dominant lesions on RP: 50 R lobe, 44 L lobe, 31 bilateral. 15/50 R lobe and 18/44 L lobe dominant tumors had LN metastasis on the contralateral side. Only 4% of cases were associated with anterior dominant tumors. 3040% of LN metastases occur contralateral to the dominant tumor. LN metastasis is overwhelmingly associated with high grade, high stage and large volume disease. LN positivity is rarely associated with anterior dominant tumors.

How To Know If Prostate Cancer Has Spread To Lymph Nodes : File Diagram ...

Patients with suspicious lymph nodes at imaging represent approximately 12% of all new PCa diagnosis.2 This rate is likely to increase within the next few years given the greater utilization of advanced preoperative imaging ,3 and a trend towards higher rates of newly diagnosed non-local confined disease observed during the past decade.4 The presence of clinical nodal metastases is associated with detrimental oncologic outcomes. As such, patients with node positive PCa are considered to have stage IV disease based on the National Comprehensive Cancer Network guidelines.6 In these guidelines, no distinction is made between distant metastatic disease and lymph node metastatic disease . Therefore, systemic therapies should be considered in PCa patients with suspicious lymph nodes at diagnosis.7

Targeted and gentle removal of affected lymph nodes without irradiation or surgery

Illustration 1: The lymphatic system.1

Prostate cancer often spreads into the surrounding lymph nodes. This is called lymph node metastases. The standard treatment is the surgical removal of all pelvic lymph nodes, which is a substantial intervention. Targeted radiation therapies can be an alternative, but these therapies severely restrict the options of follow-up treatments, which are unfortunately often necessary in case of scattered cancer. With NanoKnife, there now is the possibility for high-precision and minimally invasive treatment of lymph node metastases without radiation or surgery.

What are lymph nodes and lymph node metastases?

Lymph nodes are up to one centimeter large, bean-shaped organs, which are interlinked and connected to the so-called lymphatic system. They are also part of the immune system. In the lymph system, instead of blood, lymph fluid is transported. In this system the lymph nodes are the stations, where the lymph is filtered.

Lymph node metastases are the scattered cancer cells in lymph nodes . They usually cause no symptoms. Usually they are detected either by modern imaging techniques or by the histological analysis of the lymph nodes themselves, when removed prophylactically during a surgery.

The first important step: the precise diagnosis

Modern Management Of Lymph Node

The presence of lymph node involvement represents one of the most relevant prognostic factors in prostate cancer patients, where individuals with LNI exhibit an unfavorable natural history compared with their counterparts without nodal metastases.1 In this review, we examined the contemporary management of node positive PCa patients. First, we will focus on patients with clinical lymph node positive PCa and second, we will examine the management of patients with LNI at final pathology.

What Is Advanced Prostate Cancer

Advanced prostate cancer is cancer that has spread from the prostate to other parts of the body. It develops when prostate cancer cells move through the blood stream or lymphatic system.

Watch our video about advanced prostate cancer.

You might hear cancer that has spread described as metastatic prostate cancer, secondary prostate cancer, secondaries, metastases or mets. It is still prostate cancer, wherever it is in the body.

Prostate cancer can spread to any part of the body, but most commonly to the bones and lymph nodes. Lymph nodes are part of your lymphatic system, which is part of the bodys immune system. Lymph nodes are found throughout the body including in the pelvic area, near the prostate.

Advanced prostate cancer can cause symptoms, such as fatigue , bone pain, and problems urinating.

The symptoms you have will depend on where the cancer has spread to. Speak to your doctor or nurse if you have any symptoms. There are treatments available to help manage them.

Its not possible to cure advanced prostate cancer. But treatments can help keep it under control and manage any symptoms.

Lymph Nodes And What They Do

What is advanced prostate cancer?

Lymph vessels send lymph fluid through nodes throughout the body. Lymph nodes are small structures that work as filters for foreign substances, such as cancer cells and infections. They contain immune cells that can help fight infection by attacking and destroying germs that are carried in through the lymph fluid. Lymph nodes are located in many parts of the body, including the neck, armpit, chest, abdomen , and groin. They contain immune cells that can help fight infection by attacking and destroying germs that are carried in through the lymph fluid.

There are hundreds of lymph nodes throughout the body. Each lymph node filters the fluid and substances picked up by the vessels that lead to it. Lymph fluid from the fingers, for instance, works its way toward the chest, joining fluid from the arm. This fluid may filter through lymph nodes at the elbow, or those under the arm. Fluid from the head, scalp, and face flows down through lymph nodes in the neck. Some lymph nodes are deep inside the body, such as between the lungs or around the bowel, to filter fluid in those areas.

Cancer Cells Dodge Attack On The Way To Lymph Nodes

Next, the researchers asked what gives some melanoma cells the ability to spread to the lymph nodes.

They found that cancer cells that had spread to the lymph nodes had higher levels of certain proteins, including PD-L1 and MHC-I, than melanoma cells that didnt spread. High levels of PD-L1 and MHC-I send signals that tell cancer-fighting immune cells not to attack.

Further studies confirmed that higher levels of PD-L1 and MHC-I shielded melanoma cells from attack by immune cells. More specifically, immune cells called NK cells killed fewer melanoma cells that spread to the lymph nodes than melanoma cells that didnt spread.

Its quite remarkable what to dodge on the way to the lymph nodes. There is lots of immune attack, Dr. Engleman explained.

What Is Cancer Of The Lymph Nodes

When cancer originates in the lymph nodes or other areas of the lymphatic system, its referred to as lymphoma.2 The most common types are hodgkins lymphoma and non-hodgkins lymphoma. In rare instances, theres also a chance for the development of lymphoma of the skin. If youre wondering, Is lymphoma hereditary, we cover this question in our latest blog article.

People with hodgkins lymphoma usually experience enlarged lymph nodes with a small number of Reed-Sternberg cells present surrounded by normal immune cells. With classic hodgkins lymphoma, which accounts for 9 out of 10 cases of this type of cancer, there are four subtypes that may develop.3 These are:

  • Nodular sclerosis hodgkins lymphoma is the most common and tends to start in the lymph nodes in the neck or chest. Though it is more prevalent in teens and young adults, it can develop at any age.
  • Mixed cellularity hodgkins lymphoma is the second most common subtype and occurs mainly in the lymph nodes found in the upper half of the body. Its mostly detected in people with HIV infection and affects mostly children and the elderly.
  • Lymphocyte-rich hodgkins lymphoma is a rarer subtype and usually occurs in the upper half of the body in a few lymph nodes.
  • Lymphocyte-depleted hodgkins lymphoma is the rarest subtype of this type of cancer and occurs mainly in older people with HIV infection. Its mostly found in lymph nodes in the stomach, spleen, liver, and/or bone marrow.

Although direct comparison of different trials is a flawed approach, their collective results do provide interesting insights. At the same time as the EORTC was enrolling patients on protocol 30846, the Eastern Cooperative Oncology Group launched a randomized trial of immediate vs deferred ADT in patients who were found to have pathologically involved lymph nodes at the time of RP, but in contrast to the EORTC trial, these patients underwent RP and were randomly assigned to receive immediate, continuous ADT , or to be followed up and receive ADT when clinical recurrence was detected . With a median follow-up of 11.9 years, median overall survival was 13.9 vs 11.3 years in the immediate-ADT and delayed-ADT groups, respectively. In the immediate-ADT group, 41% of patients died of PCa compared with 89% in the delayed-ADT group.
